Electro-nuclear transition into a spatially modulated magnetic state in YbRhSi
J. Knapp, L. V. Levitin, J. Nyéki +7
The nature of the antiferromagnetic order in the heavy fermion metal YbRhSi, its quantum criticality, and superconductivity, which appears at low mK temperatures, remain op…
Solution to the Gliding Tone Problem
Brian Cowan, Andrew Morris-Costigliola, George Nichols
The solution is given to the classical problem of an oscillator driven by a sinusoid of steadily-varying frequency. A closed analytical expression is obtained in the case where the…
Evidence for a Spatially-Modulated Superfluid Phase of He under Confinement
Lev V. Levitin, Ben Yager, Laura Sumner +6
In superfluid He-B confined in a slab geometry, domain walls between regions of different order parameter orientation are predicted to be energetically stable. Formation of the…
Study of superfluid He under nanoscale confinement. A new approach to the investigation of superfluid He films
Lev Levitin, Robert Bennett, Andrew Casey +7
We review recent experiments in which superfluid He has been studied under highly controlled confinement in nanofluidic sample chambers. We discuss the experimental challenges…
Frequency Dependence of the Supersolid Signature in Polycrystalline 4He
George Nichols, Malcolm Poole, Jan Nyeki +2
We report studies, using a two mode torsional oscillator, of the putative supersolid signature in polycrystalline 4He. Measurements at two frequencies enable us to eliminate the vi…
Quantum transport in mesoscopic He films: experimental study of the interference of bulk and boundary scattering
P. Sharma, A. Córcoles, R. G. Bennett +4
We discuss the mass transport of a degenerate Fermi liquid He film over a rough surface, and the film momentum relaxation time, in the framework of theoretical predictions. In…
