15
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.
16
Cold Atoms Creation of a Fermionic System in the
unitary regime of 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.
17
Supersolids Robust observations in behavior for
all the Penn State torsional oscillator
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 flow transverse sound 4th
sound But rotating cryostat may be showing
something high frequency, low amplitude sound
resonances Paris melting curve experiment and
the grain boundary interpretation, consistent
with those experiments.
18
More on Supersolids Some important
questions Is the reported interpretation of a
critical velocity really a critical velocity? Or,
is it a critical amplitude or acceleration? Is
the grain boundary interpretation relevant to
experiments at higher pressure? What will
torsional oscillator results be like when samples
are grown be 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?
19
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.
20
  • 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-D physics in the pores, (2) Adsorption
    phenomena, e.g.
  • on nanotube bundles
  • Quantum phase transitions in porous media

21
Other interesting results Visualization of
magnetic domains in U2D2 3He. Optical modes in
solid 4He Phase synchronization in aperture
arrays potential for High precision gyroscopes.
Behavior of the phase near Lambda transition
(SOC). Electric induction in He II counterflow.
