The stochastic limit in the analysis of the open BCS model

Mathematical Physics 2009-11-13 v1 math.MP

Abstract

In this paper we show how the perturbative procedure known as {\em stochastic limit} may be useful in the analysis of the Open BCS model discussed by Buffet and Martin as a spin system interacting with a fermionic reservoir. In particular we show how the same values of the critical temperature and of the order parameters can be found with a significantly simpler approach.
