Generalized Supersymmetric Perturbation Theory
Abstract
Using the basic ingredient of supersymmetry, a simple alternative approach is developed to perturbation theory in onedimensional nonrelativistic quantum mechanics. The formulae for the energy shifts and wavefunctions do not involve tedious calculations which appear in the available perturbation theories. The model applicable in the same form to both the ground state and excited bound states, unlike the recently introduced supersymmetric perturbation technique which, together with other approaches based on logarithmic perturbation theory, are involved within the more general framework of the present formalism.
