Participation in LCGT (KAGRA) Collaboration from Shanghai

Group: progress report

Xiang-hua Zhai

Shanghai Normal University

f2f meeting of LCGT, Feb. 2-4,2012

Initiation

• August, 2010

• Professor Kuroda visited SUCA, Shanghai Normal University, SUCA organized a collaboration discussion and Professor Kuroda gave a talk on LCGT and GW detection

• At this discussion, collaboration agreement was drafted.

What we have done in the Feb. 3-11, 2011 f2f meeting and

after-meeting visit

• Xiang-hua Zhai and Ping Xi attended f2f meeting

• Giving statements on the interests in quantum scheme and data

analysis

• Approved to become international collabration members in the meeting

• Visited NAOJ, KEK and Wasda University

• Discussed with Profs. Kanda and Somiya on detailed collabration

directions

April 2011

• The agreement on the collabration between SUCA and ICRR was signed.

Aug. 19-20, 2011• Prof. Takaaki Kajita visited SHNU.

• We organized a Mini-workshop on GW detection to enlarge the

collabration in Shanghai area.

• 25 people from East China Normal University (Prof. Long-sheng Ma

and his group), Shanghai Jiaotong University, East China University

of Science and Technology, Shanghai University,

Shanghai Astronomical Observatory(SHAO), Shanghai Institute of

Ceramics(SIC) and SHNU attended the workshop.

• 4 talks (Prof. Takaaki Kajita, Prof. Wei-tou Ni, Dr. Jing Zeng from

SHAO, Dr. Li-he Zheng from SIC)

• Discussed on further collaboration and joint research potential in

Shanghai area regarding to LCGT.

• Prof. Kajita visited SIC and, together with SUCA, set the next visit

of Japanese expert(s) to Shanghai in September.

Sep. 21-23, 2011

• Prof. Norikatsu Mio visited SHNU and SIC

• Mini-workshop: 3 talks ( Profs. Mio, Ni and Zhai)

• Deep discussion on further collabration and acceleration of

substantial progress .

• Prof. Mio and Prof. Ni visited the Sapphire factory in Xuzhou and

discussed the manufacture of sapphire crystals for LCGT together

with SIC and Factory authority.

Sep. 2011

• As one core organization of China, SHNU participated in applying a JSPS fund for exchange researchers with overseas countries under the keyword of conducting gravitational wave research by LCGT.

What we will do • Our interests: quantum scheme and data analysis

• quantum scheme: We will consider how to use squeezed state to

reduce quantum noise and to consider the application in LCGT.

• data analysis: we are studying the relativistic spin double black hol

e system. We are working on the numerical method to study the wa

veform and the dynamical properties of gravitational waves in the thr

ee stages of gravitational wave radiation in order to create a comple

te template to use in LCGT data analysis .

• Xiang-hua Zhai and Ping Xi intend to attend the f2f meeting in Aug.

• Our graduate students have had the initial concept on GW detection

through several talks and some of them are interested in the LCGT

project.
