Confluent Second-Order Supersymmetric Quantum Mechanics and Spectral Design
arXiv:1909.06632 · doi:10.1088/1402-4896/ab4be2
Abstract
The confluent second-order supersymmetric quantum mechanics, in which the factorization energies tend to a common value, is used to generate Hamiltonians with known spectra departing from the hyperbolic Rosen-Morse and Eckart potentials. The possible spectral modifications, as to create a new level or to delete a given one, as well as the isospectral transformations, are discussed.
