Suppression of Modes in the Random Phase Approximation
Suppression of Modes in the Random Phase Approximation
Dönau, F.
A general but simple method is proposed to eliminate the quantum fluctuations generated by selected one-body operators in the excitation spectrum of a discrete random phase approximation (RPA) Hamiltonian. This method provides an outstanding tool for the removal of the contaminating spurious effects originated from symetry violations. It can be also applied as a mode filter for analyzing RPA response functions.
