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…
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…
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…
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…
Daily modulations and broadband strategy in axion searches. An application with CAST-CAPP detector
F. Caspers, C. M. Adair, K. Altenmüller +60
It has been previously advocated that the presence of the daily and annual modulations of the axion flux on the Earth's surface may dramatically change the strategy of the axion se…
Competing Electronic Configurations for PuTe and New Insight on Plutonium Metal
J. J. Joyce, K. S. Graham, J. -X. Zhu +7
The electronic structure of plutonium metal and its compounds pose a grand challenge for a fundamental understanding of the Pu-5 electron character. For 30 years the plutonium c…
