The A–B transition in superfluid 3He is a pure experimental model system to study first-order phase transitions in the early Universe. Tian et al. observe the path dependence of the supercooling of the A phase in a wide parameter range and provide

Surface states in topological quantum matter are protected by their band structure. Here, on confined superfluid 3He as a model for topological superconductors, the authors report experimental evidence on the fragility of surface Andreev bound states

Superfluid 3He under confinement can be used as a model system for topological quantum matter, but few related measurements are reported. Here, the authors report on the thermal conduction of helium-3 in a micro-fabricated channel with unanticipated

Superfluid helium-3 provides a clean testing ground for the understanding of quantum phases and their transitions. Here the authors show that when helium is confined in a nanofluidic cavity supercooling across the first-order A–B transition is supp

Anisotropic disorder is predicted to change the stability of the superfluid state in3He and leads to new phases. Here, Zhelev et al. report signatures of the phase transitions in 3He confined in an extremely anisotropic ordered aerogel including a ne

Superfluid 3He, with unconventional spin-triplet p-wave pairing, provides a model system for topological superconductors, which have attracted significant interest through potential applications in topologically protected quantum computing. In topolo

We report on the design of a torsion pendulum that can resolve the mass loading from 5×10 17 3 He atoms (equivalent to a 1000A film) with a 0.1% resolution. The oscillator is fabricated from coin silver alloy, and the working surfaces are two highly

We discuss the mass transport of a degenerate Fermi liquid ^{3}He film over a rough surface, and the film momentum relaxation time, in the framework of theoretical predictions. In the mesoscopic regime, the anomalous temperature dependence of the rel

We present measurements of the slip of normal 3 He contained between a pair of highly polished silicon plates mounted on a torsional oscillator. The resulting effective viscosity of pure normal 3 He is not consistent with simple slip theory and shows

We report resistive measurements on a thin-film analog of a modulated-transition-temperature superlattice. The aluminum film was reactive-ion etched in strips perpendicular to the current path, decreasing {ital T}{sub {ital c}} of the etched sections
