Alternative approach to nonrelativistic perturbation theory

Il-W Kim, U. Sukhatme

The authors develop a simple alternative approach to perturbation theory in one-dimensional nonrelativistic quantum mechanics. The formulae for the energy shifts and wavefunctions do not involve cumbersome sums over intermediate states which appear in the usual Rayleigh-Schrodinger expansion. Unlike standard logarithmic perturbation theory, the approach does not utilize taking the logarithm of the wavefunction, and is therefore applicable in the same form to both the ground state and excited bound states.The authors develop a simple alternative approach to perturbation theory in one-dimensional nonrelativistic quantum mechanics.
