[44.12] Accurate and Efficient Perturbation Theory by Matrix Inversion

B.C. Reed (Alma College)

A novel approach to time-independent quantum-mechanical perturbation theory is developed which has significant advantages over the traditional Rayleigh-Schroedinger method. With this new method, energies and wavefunctions corresponding to perturbations of arbitrary strength acting on either degenerate or nondegenerate systems can be efficiently recovered in a conceptually straightforward matrix-inversion scheme. Tedious summations are eliminated, and no integrals beyond those appearing in first-order perturbation theory need be computed.
