We provide, for a given vortex configuration, a general approach to the solution of the Lawrence-Doniach model in the London approximation including Josephson coupling between the layers at the linear level. Then, the scheme is used to investigate some properties of vortex-antivortex pairs which are relevant for the intrinsic critical current introduced by Jensen and Minnhagen.

Abstract
We provide, for a given vortex configuration, a general approach to the solution of the Lawrence-Doniach model in the London approximation including Josephson coupling between the layers at the linear level. Then, the scheme is used to investigate some properties of vortex-antivortex pairs which are relevant for the intrinsic critical current introduced by Jensen and Minnhagen. We also study the stability of tilted flux lines.File in questo prodotto:
