In this article, we give a comprehensive review of recent progress in research on symmetry-
protected topological superfluids and topological crystalline superconductors, and their …

Superfluid He 3 under nanoscale confinement has generated significant interest due to the
rich spectrum of phases with complex order parameters that may be stabilized. Experiments …

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 …

Direct detection of gravitational waves is opening a new window onto our universe. Here, we
study the sensitivity to continuous-wave strain fields of a kg-scale optomechanical system …

This paper reviews confinement-driven phase transitions in superconductors and Bardeen–
Cooper–Schrieffer superfluids, and the appearance in thin films of new phases that break …

Micro-and nanomechanical resonators with ultralow dissipation have great potential as
useful quantum resources. The superfluid micromechanical resonators presented here …

Superfluid helium confined to nanofluidic systems is emerging as an important system for
studies of two-dimensional turbulence and as the basis for novel quantum technologies. In …

Superfluid He 4 (He II) is a widely studied model system for exploring finite-size effects in
strongly confined geometries. Here, we study He II confined in millimeter-scale channels of …

Turbulent flow restricted to two dimensions can spontaneously develop order on large
scales, defying entropy expectations and in sharp contrast with turbulence in three …

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 …
