Self-Consistent RPA Based on the Thermo Field Dynamics

Abstract

The conventional RPA is extended to take into account the effect of the Pauli principle and the ground-state correlations based on the thermo field dynamics formalism. The calculations have been performed for the dipole state in the scheme of 58 nucleons within the degenerate schematic model. A comparison of these results with the calculations carried out within the framework of the standard thermo field dynamics of the RPA is made.
