Strictly isospectral potentials from excited quantum states
arXiv:quant-ph/0008067
Abstract
The strictly nonrelativistic isospectral scheme based on the general Riccati solution and Darboux transformation function corresponding to excited states is presented on the following examples: the harmonic oscillator, the square well, and the hydrogen atom
