Equations-of-motion method including renormalization and double-excitation mixing*


The equations-of-motion method is discussed as an approach to calculating excitation energies and transition moments directly. The proposed solution [T. Shibuya and V. McKoy, Phys. Rev. A 2, 2208 (1970)) of these equations is extended in two ways. First we include the proper renormalization of the equations with respect to the ground state particle-hole… (More)
