Impurity Effects of Aerogel in Superfluid He
W. P. Halperin, H. Choi, J. P. Davis +1
The discovery of superfluid He in high porosity silica aerogels, and subsequent experimental and theoretical work, have led to a better general understanding of quasiparticle…
Stability of the A-like Phase of Superfluid 3He in Aerogel with Globally Anisotropic Scattering
J. P. Davis, J. Pollanen, B. Reddy +3
It has been suggested that anisotropic quasiparticle scattering will stabilize anisotropic phases of superfluid He contained within highly porous silica aerogel. For example, g…
Strong Coupling Corrections to the Ginzburg-Landau Theory of Superfluid ^{3}He
H. Choi, J. P. Davis, J. Pollanen +2
In the Ginzburg-Landau theory of superfluid He, the free energy is expressed as an expansion of invariants of a complex order parameter. Strong coupling effects, which increa…
Magneto-Acoustic Spectroscopy in Superfluid 3He-B
J. P. Davis, H. Choi, J. Pollanen +1
We have used the recently discovered acoustic Faraday effect in superfluid 3He to perform high resolution spectroscopy of an excited state of the superfluid condensate. With acoust…
Ultrasound attenuation of superfluid He in aerogel
H. C. Choi, N. Masuhara, B. H. Moon +7
We have performed longitudinal ultrasound (9.5 MHz) attenuation measurements in the B-phase of superfluid He in 98% porosity aerogel down to the zero temperature limit for a wi…
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…
