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…

Low temperature thermal resistance for a new design of silver sinter heat exchanger

J. Pollanen, H. Choi, J. P. Davis +2

We have developed a novel procedure for constructing high surface area silver sinter heat exchangers. Our recipe incorporates nylon fibers having a diameter of ~ 50 microns and thi…

Superfluid Phase Stability of He in Axially Anisotropic Aerogel

J. Pollanen, J. P. Davis, B. Reddy +3

Measurements of superfluid He in 98% aerogel demonstrate the existence of a metastable \emph{A}-like phase and a stable \emph{B}-like phase. It has been suggested that the rela…

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…
