Monopole, half-quantum vortices and nexus in chiral superfluids and superconductors

Abstract

Two exotic objects are still not identified experimentally in chiral superfluids and superconductors. These are the half-quantum vortex, which plays the part of the Alice string in relativistic theories, and the hedgehog in the l-field, which is the counterpart of the Dirac magnetic monopole. These two objects of different dimensionality are topologically connected. They form the combined object which is called nexus in relativistic theories (hep-th/9911125). Such combination will allow us to observe half-quantum vortices and monopoles in several realistic geometries.
