Generalized Wick's theorem for multiquasiparticle overlaps as a limit of Gaudin's theorem

Abstract

We are able to rederive in a very simple way the standard generalized Wick's theorem for overlaps of mean field wave functions by using the extension of the statistical Wick's theorem (Gaudin's theorem) in the appropriate limits.
