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…

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…

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…
