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…
High frequency sound in superfluid 3He-B
J. P. Davis, H. Choi, J. Pollanen +1
We present measurements of the absolute phase velocity of transverse and longitudinal sound in superfluid 3He-B at low temperature, extending from the imaginary squashing mode to n…
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…
Collective Modes and f-wave Pairing Interactions in Superfluid 3He
J. P. Davis, H. Choi, J. Pollanen +1
Precision measurements of a collective mode in superfluid 3He B are sensitive to quasiparticle and f wave pairing interactions. Measurements were performed at various pressures usi…
Acoustic Spectroscopy of Superfluid 3He in Aerogel
J. P. Davis, H. Choi, J. Pollanen +1
We have designed an experiment to study the role of global anisotropic quasiparticle scattering on the dirty aerogel superfluid 3He system. We observe significant regions of two st…
Magnetoresistance of UPt3
T. M. Lippman, J. P. Davis, H. Choi +2
We have performed measurements of the temperature dependence of the magnetoresistance up to 9 T in bulk single crystals of UPt3 with the magnetic field along the b axis, the easy m…
