An Improvement on RPA Based on a Boson Description

Shi-Lin Zhu, Zhi-Ning Zhou, Ze-sen Yang

Abstract

We use a solvable model to perform modified Dyson mapping and reveal the unphysical-state effects in the original random phase approximation (RPA). We then propose a method to introduce the RPA and improve it based on the boson description.

Extended RPA within a solvable 3 level model

F. Catara, M. Grasso, Michelangelo Sambataro

Working within an exactly solvable 3 level model, we discuss am extension of the Random Phase Approximation (RPA) based on a boson formalism. A boson Hamiltonian is defined via a mapping procedure and its expansion truncated at four-boson terms. RPA-type equations are then constructed and solved iteratively. The new solutions gain in stability with respect to the RPA ones. We perform diagonalizations of the boson Hamiltonian in spaces containing up to four-phonon components. Approximate spectra exhibit an improved quality with increasing the size of these multiphonon spaces. Special attention is addressed to the problem of the anharmonicity of the spectrum.

Boson-mapping-based extension of the random-phase approximation in a three-level Lipkin model

M. Grasso, F. Catara, Michelangelo Sambataro

Working within an exactly solvable three level model a boson Hamiltonian is defined via a mapping procedure and its expansion truncated at four-boson terms. The resulting spectrum is found in good agreement with the exact one. We discuss an extension of the random-phase approximation (RPA) based on this boson formalism. Nonlinear RPA-type equations are constructed and solved iteratively. The new solutions gain in stability with respect to the RPA ones. We perform diagonalizations of the boson Hamiltonian in restricted spaces; approximate spectra exhibit an improved quality with increasing the size of these spaces. Special attention is addressed to the problem of the anharmonicity of the spectrum.
