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…
HeLIOS: The Superfluid Helium Ultralight Dark Matter Detector
M. Hirschel, V. Vadakkumbatt, N. P. Baker +4
The absence of a breakthrough in directly observing dark matter (DM) through prominent large-scale detectors motivates the development of novel tabletop experiments probing more ex…
Precision measurements of the zero temperature dielectric constant and density of liquid He
R. T. Learn, E. Varga, V. Vadakkumbatt +1
The resonant frequencies of three-dimensional microwave cavities are explicitly dependent on the dielectric constant of the material filling the cavity, making them an ideal system…
Prototype Superfluid Gravitational Wave Detector
V. Vadakkumbatt, M. Hirschel, J. Manley +3
We study a cross-shaped cavity filled with superfluid He as a prototype resonant-mass gravitational wave detector. Using a membrane and a re-entrant microwave cavity as a sensi…
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…
Stabilized Pair Density Wave via Nanoscale Confinement of Superfluid He
A. J. Shook, V. Vadakumbatt, P. Senarath Yapa +8
Superfluid He under nanoscale confinement has generated significant interest due to the rich spectrum of phases with complex order parameters that may be stabilized. Experiment…
Cryogenic Microwave Filter Cavity with a Tunability Greater than 5 GHz
T. J. Clark, V. Vadakkumbatt, F. Souris +2
A wide variety of applications of microwave cavities, such as measurement and control of superconducting qubits, magnonic resonators, and phase noise filters, would be well served…
