Specific Heat of Disordered He
H. Choi, J. P. Davis, J. Pollanen +2
Porous aerogel is a source of elastic scattering in superfluid 3He and modifies the properties of the superfluid, suppressing the transition temperature and order parameter. The sp…
Compressed Silica Aerogels for the Study of Superfluid 3He
J. Pollanen, H. Choi, J. P. Davis +5
We have performed Small Angle X-ray Scattering (SAXS) on uniaxially strained aerogels and measured the strain-induced structural anisotropy. We use a model to connect our SAXS resu…
Analysis of Strong-Coupling Parameters for Superfluid 3He
H. Choi, J. P. Davis, J. Pollanen +2
Superfluid He experiments show strong deviation from the weak-coupling limit of the Ginzburg-Landau theory, and this discrepancy grows with increasing pressure. Strong-coupli…
Imaginary Squashing Mode Spectroscopy of Helium Three B
J. P. Davis, H. Choi, J. Pollanen +1
We have made precision measurements of the frequency of a collective mode of the superfluid 3He-B order parameter, the J=2- imaginary squashing mode. Measurements were performed at…
Surface Specific Heat of He and Andreev Bound States
H. Choi, J. P. Davis, J. Pollanen +1
High resolution measurements of the specific heat of liquid He in the presence of a silver surface have been performed at temperatures near the superfluid transition in the p…
