A REFORMULATION OF THE THEORY OF PAIRING CORRELATIONS

Abstract

A variational approach to the ground state of a many-fermion system is developed with the trial function of condensed pairs proposed by Blatt. The calculation of matrix elements is done by a diagrammatic method which is much simpler than Blatt's. The method is susceptible of generalization to higher correlations. It is also shown that the theory is identical with HartreeBogolyubov theory. The Hartree-Bogolyubov equations are derived from the variational point of view. (Author)
