Academic Credentials
The problem has fueled intense debates in recent years and is generally con-sidered fundamental for the advancement in the field As for the proposed so-lution [by Ahluwalia] I find the approach advocated in the project a very solidone and remarkably devoid of speculative excesses common in the field thewhole program is firmly rooted in quantum field theoretic fundamentals andcan potentially contribute to them If Elko and its siblings can be shown toaccount for dark matter it will be a major theoretical advancement that willnecessitate the rewriting of the first few chapters in any textbook in quan-tum field theory If not the enterprise will still have served its purpose inelucidating the role of all representations of the extended Poincare group

Best lecturer I have come across in my 4 years at Canterbury in 2 depart-ments Amazing energy and zealous enthusiasm made a real difference tothis course if only all lecturers were as fantastic as ours has been May beone of the reasons I would stay at Canterbury
From a 2006 UC Student Survey for Phys312
Electromagnetism U of Canterbury Christchurch
The pace was perfect The use of narrative at times made the classes veryenjoyable and easier to understand The derivation nature of the course reallymade me engage in the physics rather than just accepting equations and longmathematical calculations like in other courses Overall a brilliant course
From a 2011 UC Student Survey of Phys414
Relativistic Electrodynamics and Quantum Mechanics U of Canterbury Christchurch
This was an extremely interesting amp well taught course that really stimulatedmy interests Dharam is an excellent teacher amp explained things clearlyelucidating the physical motivations behind the equations amp giving a cohesiveapproach to the topic

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)
7See H Georgi and S L GlashowldquoNeutrinos on earth and in the heavensrdquo Phys Rev D 61 (2000)097301 [e-print hep-ph9808293]

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8
8D V Ahluwalia and C Burgard ldquoGravitationally Induced Quantum Mechanical Phases and Neu-trino Oscillations in Astro-Physical Environmentsrdquo Gen Rel Grav 28 (1996) 1161 [gr-qc9603008] ldquoNeutrino oscillations and supernovaerdquo Addendum-ibid 36 (2004) 2183 [astro-ph0404055] D V Ahluwalia and C Burgard Interplay of gravitation and linear superpositionof different mass eigenstates Phys Rev D 57 (1998) 4724 [gr-qc9803013] Presently these carry106 and 61 citations respectively They have influenced a far greater number of researches than thesecitations indicate The most important of the publications in this category is the 2004 Addendum

mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

These papers argued that in any theory of quantum gravity the meaning of lsquoquantumrsquoand lsquogravityrsquo suffers a fundamental change The last paper within a specific context ob-tained an explicit modification to lsquoλ = hprsquo of de Broglie and established its implicationsfor neutrino oscillations in the early universe

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way
48
Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way
48
Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

mdash Best lecturer I have come across in my 4 years at Canterbury in 2 departmentsAmazing energy and zealous enthusiasm made a real difference to this course ifonly all lecturers were as fantastic as ours has been May be [sic] one of the reasonsI would stay at Canterbury
mdash This was the best physics course I have taken as it linked everything I had previ-ously learnt as separate phenomena
mdash He could not be more passionate about physics
mdash Showed how various areas of physics are all interconnected Hugely inspirationallecturer overall Very motivating series of lectures on an area I expected to find abit of a chore excellent
mdash He gave me more inspiration than all other lecturerrsquos combined he not onlyassisted my learning he also encourages independent learning and thinking

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)
7See H Georgi and S L GlashowldquoNeutrinos on earth and in the heavensrdquo Phys Rev D 61 (2000)097301 [e-print hep-ph9808293]

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8
8D V Ahluwalia and C Burgard ldquoGravitationally Induced Quantum Mechanical Phases and Neu-trino Oscillations in Astro-Physical Environmentsrdquo Gen Rel Grav 28 (1996) 1161 [gr-qc9603008] ldquoNeutrino oscillations and supernovaerdquo Addendum-ibid 36 (2004) 2183 [astro-ph0404055] D V Ahluwalia and C Burgard Interplay of gravitation and linear superpositionof different mass eigenstates Phys Rev D 57 (1998) 4724 [gr-qc9803013] Presently these carry106 and 61 citations respectively They have influenced a far greater number of researches than thesecitations indicate The most important of the publications in this category is the 2004 Addendum

mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

These papers argued that in any theory of quantum gravity the meaning of lsquoquantumrsquoand lsquogravityrsquo suffers a fundamental change The last paper within a specific context ob-tained an explicit modification to lsquoλ = hprsquo of de Broglie and established its implicationsfor neutrino oscillations in the early universe

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al

Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals

A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way
48
Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way
48
Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

mdash Best lecturer I have come across in my 4 years at Canterbury in 2 departmentsAmazing energy and zealous enthusiasm made a real difference to this course ifonly all lecturers were as fantastic as ours has been May be [sic] one of the reasonsI would stay at Canterbury
mdash This was the best physics course I have taken as it linked everything I had previ-ously learnt as separate phenomena
mdash He could not be more passionate about physics
mdash Showed how various areas of physics are all interconnected Hugely inspirationallecturer overall Very motivating series of lectures on an area I expected to find abit of a chore excellent
mdash He gave me more inspiration than all other lecturerrsquos combined he not onlyassisted my learning he also encourages independent learning and thinking

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

mdash Best lecturer I have come across in my 4 years at Canterbury in 2 departmentsAmazing energy and zealous enthusiasm made a real difference to this course ifonly all lecturers were as fantastic as ours has been May be [sic] one of the reasonsI would stay at Canterbury
mdash This was the best physics course I have taken as it linked everything I had previ-ously learnt as separate phenomena
mdash He could not be more passionate about physics
mdash Showed how various areas of physics are all interconnected Hugely inspirationallecturer overall Very motivating series of lectures on an area I expected to find abit of a chore excellent
mdash He gave me more inspiration than all other lecturerrsquos combined he not onlyassisted my learning he also encourages independent learning and thinking

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

mdash Best lecturer I have come across in my 4 years at Canterbury in 2 departmentsAmazing energy and zealous enthusiasm made a real difference to this course ifonly all lecturers were as fantastic as ours has been May be [sic] one of the reasonsI would stay at Canterbury
mdash This was the best physics course I have taken as it linked everything I had previ-ously learnt as separate phenomena
mdash He could not be more passionate about physics
mdash Showed how various areas of physics are all interconnected Hugely inspirationallecturer overall Very motivating series of lectures on an area I expected to find abit of a chore excellent
mdash He gave me more inspiration than all other lecturerrsquos combined he not onlyassisted my learning he also encourages independent learning and thinking

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

mdash Best lecturer I have come across in my 4 years at Canterbury in 2 departmentsAmazing energy and zealous enthusiasm made a real difference to this course ifonly all lecturers were as fantastic as ours has been May be [sic] one of the reasonsI would stay at Canterbury
mdash This was the best physics course I have taken as it linked everything I had previ-ously learnt as separate phenomena
mdash He could not be more passionate about physics
mdash Showed how various areas of physics are all interconnected Hugely inspirationallecturer overall Very motivating series of lectures on an area I expected to find abit of a chore excellent
mdash He gave me more inspiration than all other lecturerrsquos combined he not onlyassisted my learning he also encourages independent learning and thinking

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

mdash Best lecturer I have come across in my 4 years at Canterbury in 2 departmentsAmazing energy and zealous enthusiasm made a real difference to this course ifonly all lecturers were as fantastic as ours has been May be [sic] one of the reasonsI would stay at Canterbury
mdash This was the best physics course I have taken as it linked everything I had previ-ously learnt as separate phenomena
mdash He could not be more passionate about physics
mdash Showed how various areas of physics are all interconnected Hugely inspirationallecturer overall Very motivating series of lectures on an area I expected to find abit of a chore excellent
mdash He gave me more inspiration than all other lecturerrsquos combined he not onlyassisted my learning he also encourages independent learning and thinking

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals

A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)
7See H Georgi and S L GlashowldquoNeutrinos on earth and in the heavensrdquo Phys Rev D 61 (2000)097301 [e-print hep-ph9808293]

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8
8D V Ahluwalia and C Burgard ldquoGravitationally Induced Quantum Mechanical Phases and Neu-trino Oscillations in Astro-Physical Environmentsrdquo Gen Rel Grav 28 (1996) 1161 [gr-qc9603008] ldquoNeutrino oscillations and supernovaerdquo Addendum-ibid 36 (2004) 2183 [astro-ph0404055] D V Ahluwalia and C Burgard Interplay of gravitation and linear superpositionof different mass eigenstates Phys Rev D 57 (1998) 4724 [gr-qc9803013] Presently these carry106 and 61 citations respectively They have influenced a far greater number of researches than thesecitations indicate The most important of the publications in this category is the 2004 Addendum

mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals

A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

mdash Best lecturer I have come across in my 4 years at Canterbury in 2 departmentsAmazing energy and zealous enthusiasm made a real difference to this course ifonly all lecturers were as fantastic as ours has been May be [sic] one of the reasonsI would stay at Canterbury
mdash This was the best physics course I have taken as it linked everything I had previ-ously learnt as separate phenomena
mdash He could not be more passionate about physics
mdash Showed how various areas of physics are all interconnected Hugely inspirationallecturer overall Very motivating series of lectures on an area I expected to find abit of a chore excellent
mdash He gave me more inspiration than all other lecturerrsquos combined he not onlyassisted my learning he also encourages independent learning and thinking

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way
48
Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

These papers argued that in any theory of quantum gravity the meaning of lsquoquantumrsquoand lsquogravityrsquo suffers a fundamental change The last paper within a specific context ob-tained an explicit modification to lsquoλ = hprsquo of de Broglie and established its implicationsfor neutrino oscillations in the early universe

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified

The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way
48
Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

mdash Best lecturer I have come across in my 4 years at Canterbury in 2 departmentsAmazing energy and zealous enthusiasm made a real difference to this course ifonly all lecturers were as fantastic as ours has been May be [sic] one of the reasonsI would stay at Canterbury
mdash This was the best physics course I have taken as it linked everything I had previ-ously learnt as separate phenomena
mdash He could not be more passionate about physics
mdash Showed how various areas of physics are all interconnected Hugely inspirationallecturer overall Very motivating series of lectures on an area I expected to find abit of a chore excellent
mdash He gave me more inspiration than all other lecturerrsquos combined he not onlyassisted my learning he also encourages independent learning and thinking

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way
48
Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

mdash Best lecturer I have come across in my 4 years at Canterbury in 2 departmentsAmazing energy and zealous enthusiasm made a real difference to this course ifonly all lecturers were as fantastic as ours has been May be [sic] one of the reasonsI would stay at Canterbury
mdash This was the best physics course I have taken as it linked everything I had previ-ously learnt as separate phenomena
mdash He could not be more passionate about physics
mdash Showed how various areas of physics are all interconnected Hugely inspirationallecturer overall Very motivating series of lectures on an area I expected to find abit of a chore excellent
mdash He gave me more inspiration than all other lecturerrsquos combined he not onlyassisted my learning he also encourages independent learning and thinking

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al

Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals

A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way
48
Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way
48
Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

mdash Best lecturer I have come across in my 4 years at Canterbury in 2 departmentsAmazing energy and zealous enthusiasm made a real difference to this course ifonly all lecturers were as fantastic as ours has been May be [sic] one of the reasonsI would stay at Canterbury
mdash This was the best physics course I have taken as it linked everything I had previ-ously learnt as separate phenomena
mdash He could not be more passionate about physics
mdash Showed how various areas of physics are all interconnected Hugely inspirationallecturer overall Very motivating series of lectures on an area I expected to find abit of a chore excellent
mdash He gave me more inspiration than all other lecturerrsquos combined he not onlyassisted my learning he also encourages independent learning and thinking

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals
mdashmdashmdashmdashmdashmdashmdashmdashmdash
A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

These papers argued that in any theory of quantum gravity the meaning of lsquoquantumrsquoand lsquogravityrsquo suffers a fundamental change The last paper within a specific context ob-tained an explicit modification to lsquoλ = hprsquo of de Broglie and established its implicationsfor neutrino oscillations in the early universe

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals

A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way
48
Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al

Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals

A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals

A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way
48
Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions

We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al

Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals

A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals

A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al

Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments

Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al
mdashmdashmdashmdashmdashmdashmdashmdashmdash
Another important result that I obtained in this series of the papers was on the redshift offlavor oscillation clocks induced by gravitationally-induced phases This result combinedwith implications for supernova explosions earned me (along with Christoph Burgard)the 1996 First Prize of the Gravity Research Foundation8

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the
1996 JRO Fellowship proposal in 2004
with zero citations and a story I am happy to tell in private (and here the same is related briefly inthe next item with the title lsquoA stolen creditrsquo)

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals

A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Past
My publications can be roughly divided in three parts
mdash Neutrino oscillations and gravitationally-induced phases
mdash Interface of the gravitational and quantum realms and
mdash New constructs in quantum field theory Elko and Mass Dimension One Fermions
Elko and Mass Dimension One Fermions
In what follows I briefly remark on each of these areas by simply drawing attention tosome relevant papers and their impact
Overall at the date of this writing according to INSPIRE database I have more thantwo thousand citations with 356 citations per published paper on the average MyHirsch[h] index is 27 That is 27 of my papers have at least 27 citations
The citations change to about two thousand and eight hundred and the h index to 30if one consults Google Scholar
Neutrino oscillations and gravitationally-induced phases
I was among the very first to obtain bi-maximal mixing ndash and soon thereafter fixedatmospheric angle to be maximal and θ13 = 0 ndash from the atmospheric neutrino oscil-lations data Two of the three angles in the tribimaximal mixing were first fixed byme in collaboration with Ion Stancu The result was published first in 1998 and laterin an analytically more elegant form in 19996 When in 2012 Daya Bay and RENOcollaborations measured a non-zero θ13 I again made one of the early contribution tothe field by obtaining a CP violating Tri-bimaximal-Cabibbo mixing matrix
One of the strengths these papers represent is the immediate recognition from the dataof the underlying mixing matrix It was only later that Georgi and Glashow7 includingothers obtained the same result but under a set of several additional assumptions
6The relevant publications are (a) D V Ahluwalia Reconciling super-Kamiokande LSND and Home-stake neutrino oscillation data Mod Phys Lett A 13 (1998) 2249 [e-print hep-ph9807267] and(b) I Stancu and D V Ahluwalia LE-flatness of the electron-like event ratio in Super-Kamiokandeand a degeneracy in neutrino masses Phys Lett B 460 (1999) 431 [e-print hep-ph9903408] Thefirst of these has 91 citations and the second carries 105 citations (as of this writing)

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436
We fixed two of the three angles in what later came to be known as tribimaximalmixing Here is a lsquoscreen shotrsquo of Eq (6) of P F Harrison D H Perkins and W GScott Phys Lett B 530 (2002) 167-173
Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1
radic3) in the 1999 result of ours and that we fixed two of the three angles
This circumstance has led to an INSPIRE citation ratio of 105 1108 in favor of Harrisonet al

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals

A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields
45
bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way
48
Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

are massive vector fields and massive gravity We expect to have a monographic firstpreprint on the subject later this year In the tradition of mass dimension one fermionicfields this is expected to be a very fertile field that will answer outstanding questionsin this arena and help revise the standard model by incorporating a new massive vectorfield that introduces unitarity and re-normalizability in a very natural way ndash or at leastin a different way

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

A remark on my contribution to tri-bimaximal mixing Here is a lsquoscreen shotrsquoof Eq (26) in I Stancu and D V Ahluwalia Phys Lett B 460 (1999) 431-436

Nowhere in their 2002 paper three years after our result was published in 1999 doHarrison Perkins and Scott mention that their lsquotribimaximalrsquo follows by setting θ =arcsin(1

A remark on my contribution to of type II supernovae explosions Somewherearound 2004 I learned that my 1996 J Robert Oppenheimer Fellowship proposal at theLos Alamos National Laboratory that contained the argument that
neutrino oscillations may provide a powerful energy transport mech-anism for explosions of type II supernovae explosions
had become a mainstream idea beginning with implementations at Los Alamos It ledto a very rapid advancement in the field However I remained unaware that this ideawas implemented at Los Alamos under another JRO Fellowship supported group as myown interest shifted to foundations of quantum field theory and other problems
As of this date I have absolutely no credit for this idea fully explained in my 1996proposal The reader will notice that on learning of these facts an Editor of Gen RelGrav published my 1996 proposal in 2004 as an Addendum to my 1996 paper withChristoph Burgard
See next page for a screen shotof a very belated publication of the

Interface of the gravitational and quantum realms
My first paper on the subject9 was conceived and written over just a two-day periodIts Abstract read
This essay argues that when measurement processes involve energies of theorder of the Planck scale the fundamental assumption of locality may nolonger be a good approximation Idealized position measurements of twodistinguishable spin-0 particles are considered The measurements alter thespace-time metric in a fundamental manner governed by the commutationrelations [xi pj ] = ihδij and the classical field equations of gravitation Thisin-principle unavoidable change in the space-time metric destroys the com-mutativity (and hence locality) of position measurement operators
So far it has been cited some 135 times as recorded by the INSPIRE database Techni-cally it could have been written in a much more elegant and rigorous manner But theconceptual argument met a certain resonance with a group of physicists and encouragedmany papers related to this subject Again this impact goes far beyond the specificciting groups and individuals

A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST
See next two pages for the relevant screen shot
Doplicher et al with full knowledge of my work and securing its preprint through alsquopost cardrsquo preprint request failed to cite my preprint This circumstance has led to anINSPIRE citation ratio of 135 443 in favor of Doplicher et al With one exception tothe best of my knowledge they have systematically refrained citing this work

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present

This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)

A remark on my contribution to inevitability of non-commutative space-timeAnd again there is a story I am happy to tell in private It becomes apparent when thetwo screen shots on the next page are compared My paper was written eight monthsprior to that of Doplicher et al and who had asked for a pre-reprint of mine Theeditor of Physics Letters B published my paper after he learned of the lsquounscrupulousrsquobehavior of Doplicher Fredenhagen and Roberts This becomes apparent by comparingthe preprint dates on the KEK preprint screen shot and arXiv screen shot on the nextcouple of pages It is also worth comparing the Abstracts of my paper with that ofDoplicher et al which reads
We propose spacetime uncertainty relations motivated by Heisenbergrsquos un-certainty principle and by Einsteinrsquos theory of classical gravity Quantumspacetime is described by a non-commutative algebra whose commutationrelations do imply our uncertainty relations We comment on the classicallimit and on the first steps towards QFT over QST

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
Below I reproduce some unedited remarks from one of my courses Similar remarksappear in other surveys The copy of the original survey may be obtained on request

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory

New constructs in quantum field theory
An early work The work was initially inspired by Wignerrsquos observation that saidin modern language the fields of the standard model do not exhaust all the physically-relevant possibilities offered by the Poincare spacetime symmetries Specifically thestandard wisdom11 that for bosons the particle-antiparticle intrinsic parity is the samewhile for fermions it is opposite need not hold in general In 1993 in a paper jointlypublished with Johnson and Goldman I was able to construct the first explicit exampleof such a theory It drew the following remark from a referee of Physical Review Letters
ldquoCongratulations Indeed Bargmann Wightman and Wigner had studiedthis subject forty years ago in an unpublished book (several chapters weredistributed as preprints) The authors explain well the scope of their paperThey have made a thorough construction of a field theory of a non usualWigner type that is completely new This paper should be publishedrdquo
Yet despite no other report the paper was editorially rejected12
The entire set of reports can be found in an Acknowledgment of hep-th9509116 Themain result of this paper was that contrary to claims made in well-known papers therelative particle-antiparticle intrinsic parity for the massive (1 0)oplus (0 1) representationspace is opposite That is instead of [CP ] = 0 a careful analysis obtains CP = 0Over the last decade this result has grown into a set of papers developing several relatedresults and remain formally un-noted Yet knowledgeable physicists have taken a noteof several of these results with due respect It was partly for this reason that I wasinvited to write book reviews of Lewis Ryderrsquos and Steven Weinbergrsquos monographs onquantum field theory
11See for example L H Ryder Elementary particles and symmetries (Gordon and Breach New York1986) p 32

Statement about Research Recent and Present
An unexpected theoretical discoveryElko and Mass Dimension One Fermions
This story begins with the publication of two papers in 2005 The first sentence of eachof these papers contained the phrase lsquounexpected theoretical discoveryrsquo The lsquoscreenshotsrsquo of these two papers appear here below and in the next page They provide asummary of the essential results The non-locality reported in these seminal papers hasnow been fully resolved and is reported in a series of papers over the last decade Thereferee report below reflects significance of these papers and subsequent developmentshave proved early optimism fully justified
From a referee report of Marsden Application 07-UOC-055
The problem has fueled intense debates debates in recent years and is gen-erally considered fundamental for the advancement in the field As for theproposed solution [by Ahluwalia] I find the approach advocated in the projecta very solid one and remarkably devoid of speculative excesses common inthe field the whole program is firmly rooted in quantum field theoretic funda-mentals and can potentially contribute to them If Elko and its siblings can beshown to account for dark matter it will be a major theoretical advancementthat will necessitate the rewriting of the first few chapters in any textbook inquantum field theory If not the enterprise will still have served its purposein elucidating the role of all representations of the extended Poincare group

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

The state of affairs of my present research can perhaps be best glimpsed by reproducingthe Abstracts of some of the papers from the last few years
1 D V Ahluwalia S P Horvath Neutrino oscillations with disentanglement of aneutrino from its partners Europhys Lett 95 (2011) 10007 [5 pages]
Abstract We argue that in order to understand existing data on neu-trino oscillations and to design future experiments it is imperative toappreciate the role of quantum entanglement Once this is accountedfor the resulting energy-momentum conserving phenomenology requiresa single new parameter related to disentanglement of a neutrino fromits partners This parameter may not be CP symmetric We illustratethe new ideas with potentially measurable effects in the context of anovel experiment recently proposed by Gavrin Gorbachev Veretenkinand Cleveland The strongest impact of our ideas is on the resolution ofvarious anomalies in neutrino oscillations and on neutrino propagationin astrophysical environments
2 D V Ahluwalia and Cheng-Yang Lee Gamma-ray bursts and the relevance ofrotation-induced neutrino sterilization Phys Lett B719 (2013) 218-219
Abstract A la Pontecorvo when one defines electroweak flavour statesof neutrinos as a linear superposition of mass eigenstates one ignores theassociated spin If however there is a significant rotation between theneutrino source and the detector a negative helicity state emitted bythe former acquires a non-zero probability amplitude to be perceived asa positive helicity state by the latter Both of these states are still inthe left-Weyl sector of the Lorentz group The electroweak interactioncross sections for such helicity-flipped states are suppressed by a factorof (mνEν)2 where mν is the expectation value of the neutrino massand Eν is the associated energy Thus if the detecting process is basedon electroweak interactions and the neutrino source is a highly rotatingobject the rotation-induced helicity flip becomes very significant in in-terpreting the data The effect immediately generalizes to anti-neutrinosMotivated by these observations we present a generalization of the Pon-tecorvo formalism and discuss its relevance in the context of recent dataobtained by the IceCube neutrino telescope
These represent my continuing interest in the foundations and phenomenology of neutri-nos oscillations The primary focus however is on mass dimension one fermionic fields

bull D V Ahluwalia On a local mass dimension one Fermi field of spin one-half andthe theoretical crevice that allows it arXiv13057509 [hep-th 18 pages]
Abstract Since the 1928 seminal work of Dirac and its subsequentdevelopment by Weinberg a view is held that there is a unique Fermifield of spin one-half It is endowed with mass dimension three-halfCombined these characteristics profoundly affect the phenomenology ofthe high energy physics astrophysics and cosmology We here present acounter example by providing a local mass dimension one Fermi field ofspin one-half The theory inter alia thus allows dimensionless quarticself interaction for the new fermions and its only other dimensionlesscoupling is quadratic in the new fermions and in the standard-modelscalar field For these reasons the immediate application of the newtheory resides in the dark-matter sector of physical reality The lowest-mass associated new particle may leave its unique signature at the LargeHadron Collider We discuss in detail the theoretical crevice that allowsthe existence of the new quantum field

Statement about Research Reflections on Future
The future is the most uncertain element of onersquos life and onersquos plans One often plansor so one pretends but when the future becomes past one realises that only shadows ofthat which one had planned remain and something more organic something new andunexpected prevailed My experience shows that I am inevitably drawn into any goodidea which may be in the surrounding academic environment
It is now well known among my colleagues that I entered Los Alamos National Labo-ratory as someone involved in lsquomathematical science fictionrsquo13 and six years later leftas someone deeply immersed in experimental data connected with neutrino oscillationsand its implications for physics
That said my primary inspiration is to understand foundations of physics and its limits
I have now formed a scientific personality that is more mature than that of those earlieryears It has answered or learned to answer questions that I began with and in theprocess also opened a range of new questions On the romantic side I am now of theopinion that stabilized Poincare-Heisenberg algebra is likely to play an important role inquantum gravity (see Class Quant Grav 22 (2005) 1433-1450) Yet the mathematicaltools and physical insights required to formulate a theory along these lines appears tobe a dream that is too ambitious Nevertheless I keep it on the proverbial back burnerjust in case I am able to inspire enough critical mass of expertise to lead this project
I plan to continue my work on neutrino oscillations quantum entanglement and neutrinooscillations for neutrinos emitted by Kerr astrophysical objects This is a first-principleproject with phenomenological consequences for supernovae explosions and the propa-gation of neutrinos from the galactic center
I plan to continue my work on the role played by 4- and 3-parameter subgroups of theLorentz group the SIM(2) and HOM(2) groups of Cohen and Glashow in the contextof mass dimension one fermionic field (based on Elko see arXiv13057509) and theirimplications for dark matter Here the hope is to provide a phenomenologically viablefirst-principle dark matter candidate that is a close cousin but not an identical twin ofMajorana particles This is a field that I have fathered in significant collaboration withDaniel Grumiller Sebastian Horvath Cheng-Yang Lee and Dimitri Schritt This is alsoa field where young physicists from every continent have made their own independentcontributions At times I now feel that I am the grandfather in this field whose job it isto mentor the youngsters to help them fly with their own inspirations and expertise
A new subject where insights gained from this work may turn out to be very important

Statement about Teaching
My students and I often feel that my style of teaching carries an inspired and aninspiring element It demands sheer excellence in presentation with clarity unhurriedprogress of ideas and contact with forefront research when possible It places demandson students and places demands on me to present well-thought and well-argued lectures
The basic idea is to inspire to encourage independent thinking and to emphasize theroots of arguments while at the same time providing mathematical background necessaryto develop some of the ideas and take them from historical wisdom to the forefrontwhere they the students become part of the forefront research I aspire to carry alogical thread from my first lecture to the last so that all is connected it is a sequence oflogical development which emphasizes when contact with experiment is possible tellingwhen new paths of thinking are possible making clear those aspects which are stillun-understood or when I have doubts or questions
About a decade ago at the University of Zacatecas I taught a two-semester undergraduatecourse in Quantum Mechanics Some ten to fifteen students attended it Based onhomework problems two of these students published two papers14 One of these paperswon a Fifth Prize from Gravity Research Foundation I was able to place both of thesestudents in good graduate programs at Vanderbilt University and Syracuse University
Even as a graduate student I was asked to teach full undergraduate courses
I have no rigid philosophy about teaching
At the University of Canterbury I have taught courses in Electromagnetism (Phys312)Advanced Quantum Mechanics (Phys411) Introductory Quantum Physics (PHYS114)and Quantum Theory of Fields (Phys416) At a more junior level I have taught anintroductory course in astronomy (Astr109)
