Three-Dimensional Shape Invariant Non-Separable Model With Equidistant Spectrum

M. S. Bardavelidze, F. Cannata, M. V. Ioffe +1

A class of three-dimensional models which satisfy supersymmetric intertwining relations with the simplest - oscillator-like - variant of shape invariance is constructed. It is prov…

New Two-Dimensional Quantum Models with Shape Invariance

F. Cannata, M. V. Ioffe, D. N. Nishnianidze

Two-dimensional quantum models which obey the property of shape invariance are built in the framework of polynomial two-dimensional SUSY Quantum Mechanics. They are obtained using…

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…

Two-field cosmological models and large-scale cosmic magnetic fields

A. A. Andrianov, F. Cannata, A. Yu. Kamenshchik +1

We consider two different toy cosmological models based on two fields (one normal scalar and one phantom) realizing the same evolution of the Bang-to-Rip type. One of the fields (p…

Two-dimensional Schrödinger Hamiltonians with Effective Mass in SUSY Approach

F. Cannata, M. V. Ioffe, D. N. Nishnianidze

The general solution of SUSY intertwining relations of first order for two-dimensional Schrödinger operators with position-dependent (effective) mass is built in terms of four arbi…
