Topological Excitations and Dissipation in Superconductors and Superfluids Having Multiply Connected Geometries
Abstract
dc:descriptionDue to fluctuations, either thermal or quantum, the superflow through a sufficiently narrow channel will experience dissipation. The dissipation occurs via discrete topological excitations, called phase-slips, in which vortex lines cross the superconducting or superfluid channel. The interaction between these excitations in multiply connected geometries are studied in various settings. Rich consequences are found to occur, including the sensitivity of phase-slips to the supercurrent in the bulk superfluids connected to the thin channels, as well as avalanches of phase-slips.
