Abstract

The statistical mechanics of a vortex system in a two-dimensional superconductor is constructed using the cyclic approximation, accounting for the finiteness of the vortex core. This leads to a crossover of the vortex antivortex pair unbinding transition from the usual continuous Kosterlitz-Thouless-like behavior for large core energies to the first order transition for low energies.
