Application of the Dyson boson expansion method to the treatment of the pairing force

Document type: Articulo

Abstract

The treatment of the separable pairing interaction in the context of the BRST formalism and in the Dyson boson expansion method is discussed. The approach is based on the use of the vacuum expectation value of the boson number operator to define a suitable mean field.
