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…

New Two-Dimensional Integrable Quantum Models from SUSY Intertwining
M. V. Ioffe, J. Negro, L. M. Nieto +1
Supersymmetrical intertwining relations of second order in the derivatives are investigated for the case of supercharges with deformed hyperbolic metric . Seve…
