Thermal-field Dyson mapping for hot odd nuclei

Abstract

Two possibilities of Dyson fermion-boson realization for two-particle operators at finite temperature are derived using the thermal-field dynamic formalism. The nature of spurious states appearance in an odd-particle system is investigated. It is further observed that the matrix element of the pairing interaction between the fermion-boson basis is identical to the corresponding fermion matrix element.
