Evidence for a Spatially-Modulated Superfluid Phase of He under Confinement
Lev V. Levitin, Ben Yager, Laura Sumner +6
In superfluid He-B confined in a slab geometry, domain walls between regions of different order parameter orientation are predicted to be energetically stable. Formation of the…
Study of superfluid He under nanoscale confinement. A new approach to the investigation of superfluid He films
Lev Levitin, Robert Bennett, Andrew Casey +7
We review recent experiments in which superfluid He has been studied under highly controlled confinement in nanofluidic sample chambers. We discuss the experimental challenges…
Frequency Dependence of the Supersolid Signature in Polycrystalline 4He
George Nichols, Malcolm Poole, Jan Nyeki +2
We report studies, using a two mode torsional oscillator, of the putative supersolid signature in polycrystalline 4He. Measurements at two frequencies enable us to eliminate the vi…
Stages of Homogeneous Nucleation in Solid Isotopic Helium Mixtures
M. Poole, J. Saunders, B. Cowan
We have made pressure and NMR measurements during the evolution of phase separation in solid helium isotopic mixtures. Our observations indicate clearly all three stages of the hom…
