Deformed Shape Invariant Superpotentials in Quantum Mechanics and Expansions in Powers of $\hslash$

Abstract

We show that the method developed by Gangopadhyaya, Mallow, and their coworkers to deal with (translationally) shape invariant potentials in supersymmetric quantum mechanics and consisting in replacing the shape invariance condition, which is a difference-differential equation, by an infinite set of partial differential equations can be generalized to deformed shape invariant potentials in deformed supersymmetric quantum mechanics. The extended method is illustrated by several examples, corresponding both to $\hslash$-independent superpotentials and to a superpotential explicitly depending on $\hslash$.
