Supersymmetric Method for Constructing Quasi-Exactly Solvable Potentials
arXiv:quant-ph/9806030
Abstract
We propose a new method for constructing the quasi-exactly solvable (QES) potentials with two known eigenstates using supersymmetric quantum mechanics. General expression for QES potentials with explicitly known energy levels and wave functions of ground state and excited state are obtained. Examples of new QES potentials are considered.
