Surface-condition-mediated supercooling of the A-B transition in confined superfluid helium-3
Daksh Malhotra, Aymar Muhikira, Alexander J. Shook +1
Chiral -wave superconductors and superfluids are central model systems in the search for topological quantum matter, but in reduced dimensions their properties are inseparable f…
Bistable Fourth Sound Resonance in Superfluid He-B due to Gap Suppression
Alexander J. Shook, Daksh Malhotra, Aymar Muhikira +1
Superfluidity in He exhibits many unique properties that are of interest to modern condensed matter research, including multiple superfluid phase transitions, topological defec…
Dimensional crossover of superfluid He in a magnetic field
Leyla Saraj, Daksh Malhotra, Aymar Muhikira +3
Motivated by recent experiments on superfluid He in nanoscale-confined geometries, we theoretically investigate the associated phase diagram in a slab geometry and perpendicula…
Topologically-Protected Remnant Vortices in Confined Superfluid He
Alexander J. Shook, Daksh Malhotra, Aymar Muhikira +2
Symmetry breaking phase transitions from less to more ordered phases will typically produce topological defects in the ordered phase. Kibble-Zurek theory predicts that for any seco…
Surface State Dissipation in Confined 3He-A
Alexander J. Shook, Emil Varga, Igor Boettcher +1
We have studied the power dependence of superfluid Helmholtz resonators in flat (750 and 1800 nm) rectangular channels. In the A-phase of superfluid 3He, we observe a non-linear re…
Strong-coupling corrections to hard domain walls in superfluid 3He-B
M. J. Rudd, P. Senarath Yapa, A. J. Shook +2
Domain walls in superfluid 3He-B have gained renewed interest in light of experimental progress on confining helium in nanofabricated geometries. Here, we study the effect of stron…
Observation of bistable turbulence in quasi-two-dimensional superflow
E. Varga, V. Vadakkumbatt, A. J. Shook +2
Turbulent flow restricted to two dimensions can spontaneously develop order on large scales, defying entropy expectations and in sharp contrast with turbulence in three dimensions…
