Surface State Dissipation in Confined
We have studied the power dependence of superfluid Helmholtz resonators in flat (750 and
1800 nm) rectangular channels. In the A phase of superfluid He 3, we observe a nonlinear …

Three-tone coherent microwave electromechanical measurement of a superfluid Helmholtz resonator
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 …

Designing edge currents using mesoscopic patterning in chiral d-wave superconductors
P Holmvall, AM Black-Schaffer - arxiv preprint arxiv:2501.14563, 2025 - arxiv.org
Chiral superconductors are topological as characterized by a finite Chern number and chiral
edge modes. Direct fingerprints of chiral superconductivity is thus often taken to be …

Critical behavior and multistability in quasi-two-dimensional turbulence
Two-dimensional (2D) turbulence, despite being an idealization of real flows, is of
fundamental interest as a model of the spontaneous emergence of order from chaotic flows …

A hermetic on-cryostat helium source for low temperature experiments
KE Castoria, H Byeon, J Theis… - Review of Scientific …, 2024 - pubs.aip.org
We describe a helium source cell for use in cryogenic experiments that is hermetically
sealed in situ on the cold plate of a cryostat. The source cell is filled with helium gas at room …
