Non-perturbative Effects Near the Upper Critical Field in Type-II Superconductors

Abstract

The properties of a conventional type-II superconductor near the upper critical field are usually calculated using a perturbative expansion in the strength of the order parameter. Here we show that perturbation theory breaks down near the upper critical field and that this breakdown leads to unusual behavior near the phase transition.
