3D Non-Abelian Anyons: Degeneracy Splitting and Detection by Adiabatic Cooling
arXiv:1102.5742 · doi:10.1103/PhysRevB.84.104503
Abstract
3D non-abelian anyons have been theoretically proposed to exist in heterostructures composed of type II superconductors and topological insulators. We use realistic material parameters for a device derived from BiSe to quantitatively predict the temperature and magnetic field regimes where an experiment might detect the presence of these exotic states by means of a cooling effect. Within the appropriate parameter regime, an adiabatic increase of the magnetic field will result in a decrease of system temperature when anyons are present. If anyons are not present, the same experiment would result in heating.
