Exactly Solvable Non-Separable and Non-Diagonalizable 2-Dim Model with Quadratic Complex Interaction
F. Cannata, M. V. Ioffe, D. N. Nishnianidze
We study a quantum model with non-isotropic two-dimensional oscillator potential but with additional quadratic interaction with imaginary coupling constant. It is shown, t…

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…
