Three-Dimensional Solutions of Supersymmetrical Intertwining Relations and Pairs of Isospectral Hamiltonians
F. Cannata, M. V. Ioffe, D. N. Nishnianidze
The general solution of SUSY intertwining relations for three-dimensional Schrödinger operators is built using the class of second order supercharges with nondegenerate constant me…
Pseudo-Hermiticity of an Exactly Solvable Two-Dimensional Model
F. Cannata, M. V. Ioffe, D. N. Nishnianidze
We study a two-dimensional exactly solvable non-Hermitian non-symmetric quantum model with real spectrum, which is not amenable to separation of variables, by supersymmetrical…
Double Shape Invariance of Two-Dimensional Singular Morse Model
F. Cannata, M. V. Ioffe, D. N. Nishnianidze
A second shape invariance property of the two-dimensional generalized Morse potential is discovered. Though the potential is not amenable to conventional separation of variables, t…
Two-dimensional SUSY-pseudo-Hermiticity without separation of variables
F. Cannata, M. V. Ioffe, D. N. Nishnianidze
We study SUSY-intertwining for non-Hermitian Hamiltonians with special emphasis to the two-dimensional generalized Morse potential, which does not allow for separation of variables…
