Composite operators for BCS Superconductor

Condensed Matter 2008-02-03 v2

Abstract

The new form of the composite operator generalizing the Cooper pairs for a BCS superconductor is introduced. The approach is similar to the derivation of the composite operator of the odd - frequency superconductors. The examples of the dx2y2, dxyd_{x^2-y^2}-,~d_{xy}- and pp- wave composite operators for a 2D tJt-J model are given.
