Fermions in the vortex core in superfluids and superconductors

Abstract:  We discuss fermions localized in cores of different types of vortices in conventional and unconventional superfluids and superconductors, including anisotropic vortices, half-quantum vortices, continuous vortices, etc. The fermion zero modes on vortices give the dominating contribution to the physics of the vortex state, especially at low temperature. They determine the vortex mass, the anomalous force acting on vortices, the thermodynamics of the mixed state, etc.
