Kosterlitz-Thouless transition in uniformly confined He
Filip Novotný, Marek Talíř, Balázs Szalai +1
This study investigates the Kosterlitz-Thouless (KT) transition in superfluid He confined within uniform nanochannels. While the universal jump in superfluid density is a well-…
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…
Three-Tone Coherent Microwave Electromechanical Measurement of a Superfluid Helmholtz Resonator
Sebastian Spence, Emil Varga, Clinton A. Potts +1
We demonstrate electromechanical coupling between a superfluid mechanical mode and a microwave mode formed by a patterned microfluidic chip and a 3D cavity. The electric field of t…
Electromechanical feedback control of nanoscale superflow
Emil Varga, John P. Davis
Superfluid He is a promising material for optomechanical and electromechanical applications due to its low acoustic loss. Some of the more intriguing aspects of superfluidity -…
