SUSUSY quantum mechanics

The exactly solvable eigenproblems in Schrodinger quantum mechanics typically involve the differential ''shift operators''. In the standard supersymmetric (SUSY) case, the shift operator turns out to be of first order. In this work, I discuss a technique to generate exactly solvable eigenproblems by using second older shift operators. The links between this method and SUSY are analysed. As an example, we show the existence of a two-parametric family of exactly solvable Hamiltonians, which contains the Abraham-Moses potentials as a particular case.
