Abstract

We show that the elementary excitation of the superconductive s-wave ground state in the two-component anyon gas is always accompanied by an angular-momentum-free, flux-free vortex. Finite-temperature superconductivity in the two-component anyon gas is similar to the two-dimension superfluid. There are two Thouless-Kosterlitz (TK) phase transitions.
