RT info:eu-repo/semantics/article T1 SUSY partners and S-matrix poles of the one-dimensional Rosen–Morse II potential A1 San Millán Carpintero, Carlos A1 Gadella Urquiza, Manuel A1 Kuru, Sengul A1 Negro Vadillo, Francisco Javier K1 Hamiltonians K1 S-matrix poles K1 22 Física AB Among the list of one-dimensional solvable Hamiltonians, we find the Hamiltonian with the Rosen–Morse II potential. The first objective is to analyse the scattering matrix corresponding to this potential. We show that it includes a series of poles corresponding to the types of redundant poles or anti-bound poles. In some cases, there are even bound states and this depends on the values of given parameters. Then, we perform different supersymmetric transformations on the original Hamiltonian using either the ground state (for those situations where there are bound states) wave functions, or other solutions that come from anti-bound states or redundant states. We study the properties of these transformations.
