Functional Schrodinger Picture Formalism for Pairing Correlations

초록

To study some collective phenomena in nuclear physics, we have to understand the pairing correlation due to residual short-range correlations among the nucleons in the nucleus. This has usually been calculated by using the Bardeen-Coorper-Schrieffer theory or the Hartree-Fock-Bogoliubov theory. We introduce another approximation procedure that can be compared with those theories. We show that our approximation formalism can be applied to the nuclear shell model and is related to the Hartree-Fock-Bogoliubov approximation.
