Vortices and Turbulence
Advances in particle velocimetry to visualize vortices and turbulence in superfluids
Direct images of tracer particles – what are they imaging?
The use of Hydrogen, with ability to vary the particle size
Electron bubbles – potential to visualize vortex lines
Is the normal fluid uniform in a counterflow channel?
ULT quantum turbulence observations from Lancaster
Theory of a Twisted Vortex state
The decay of turbulence needs more theoretical study.

Cold Atoms
Creation of a Fermionic System in the unitary regimeof the BCS-BEC crossover.
Optical lattices make a bridge between atomic and solid state physics
Feshbach resonances continue to offer possibilities
Weak-Link dymanics/coherence for cold atom collections
Questions about the physics of Fermions with unbalanced spin populations are open.
The Gross-Pitaevskii equation remains important – It is remarkable how useful this equation is.

Supersolids
Robust observations in behavior for all the Penn State torsionaloscillator experiments. Very consistent and stable results over many samples in several geometries; wide pressure range.
Complete absence of clear positive results by any other technique:
pressure-driven flowtransverse sound4th sound
But:rotating cryostat – may be showing somethinghigh frequency, low amplitude sound resonances
Paris melting curve experiment – and the grain boundary interpretation, consistent with those experiments.

More on Supersolids
Some important questions:
Is the reported interpretation of a critical velocity really acritical velocity? Or, is it a critical amplitude or acceleration?
Is the grain boundary interpretation relevant to experiments athigher pressure?
What will torsional oscillator results be like when samples are grownbe techniques other than blocked capillary?
What role does annealing play?
What is the role of disorder in the solid?
Why does the NCRI have such an abrupt corner at low temperature?
What is the real role of 3He?

Superfluid 3He
Interplay between Andreev statets at a surface and the superfluid 3He collective modes
Acoustic experiments – both longitudinal and transverse
Key question: What is the nature of the A-like phase of superfluid 3He in Aerogel?
How does anisotropy in Aerogel effect superfluid 3He?
Behavior of the PCP is not agreed on.
Sample-dependent texture of the order parameter.

Confined Geometry – other than Aerogel
Quantum criticality in 2-D 3He films
Behavior of 3He in two dimensions
Low dimensional behavior in nanopores – two perspectives: (1)1-D physics in the pores, (2) Adsorption phenomena, e.g.on nanotube bundles
Quantum phase transitions in porous media
