Isospectrality of conventional and new extended potentials, second-order supersymmetry and role of PT symmetry

Author:

PRAMANA-JOURNAL OF PHYSICS


Issue Date:

Abstract(summary):

We develop a systematic approach to construct novel completely solvable rational potentials. Second-order supersymmetric quantum mechanics dictates the latter to be isospectral to some well-studied quantum systems. PT symmetry may facilitate reconciling our approach to the requirement that the rationally extended potentials be singularity free. Some examples are shown.
