Anyon superconductivity

Abstract

I enumerate the arguments which suggest that the anyon gas can exhibit superconductivity. The vortices of the superconducting anyon gas are charged and I point out some of their properties. One of the unique signatures of anyonsuperconductors is the violation of parity and the time reversal invariance. I discuss some of the experiments which are trying to look for parity and time-reversal violation in the copper oxide superconductors so as to decide if these are anyon superconductors or not.
