Anomalous Attenuation of Transverse Sound in 3He
J. P. Davis, J. Pollanen, H. Choi +3
We present the first measurements of the attenuation of transverse sound in superfluid 3He-B. We use fixed path length interferometry combined with the magneto-acoustic Faraday eff…
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…
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…
Discovery of an Excited Pair State in Superfluid 3He
J. P. Davis, J. Pollanen, H. Choi +2
Order parameter collective modes are the fingerprint of a condensed phase. The spectroscopy of these modes in superfluid He and unconventional superconductors can provide key i…
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…
