Study of superfluid ${}^3$He under nanoscale confinement. A new approach to the investigation of superfluid ${}^3$He films

Abstract

We review recent experiments in which superfluid ${}^3$He has been studied under highly controlled confinement in nanofluidic sample chambers. We discuss the experimental challenges and their resolution. These methods open the way to a systematic investigation of the superfluidity of ${}^3$He films, and the surface and edge excitations of topological superfluids.
