Polynomial algebras from and the generic model on the two sphere
Francisco Correa, Mariano A. del Olmo, Ian Marquette +1
Construction of superintegrable systems based on Lie algebras have been introduced over the years. However, these approaches depend on explicit realisations, for instance as a diff…
Tavis-Cummings models and their quasi-exactly solvable Schrödinger Hamiltonians
T. Mohamadian, J. Negro, L. M. Nieto +1
We study in detail the relationship between the Tavis-Cummings Hamiltonian of quantum optics and a family of quasi-exactly solvable Schrödinger equations. The connection between th…
Redundant poles of the -matrix for the one dimensional Morse potential
M. Gadella, A. Hernández-Ortega, Ş. Kuru +1
We analyze the structure of the scattering matrix, , for the one dimensional Morse potential. We show that, in addition to a finite number of bound state poles and an infinit…
