A Comment on the Propagator of the Radial Oscillator

Abstract

Using a hybrid approach, based on the recursion relations for shape invariant potentials developed by Das and Huang and a time-dependent tranformation of variables, we derive the propagator for a radial oscillator. Although this is not a new result, we explicitly show that time-dependent tranformations are very beneficial even within the context of time-independent Hamiltonians in quantum mechanics.
