Solution of Second Order Supersymmetrical Intertwining Relations in Minkowski Plane
M. V. Ioffe, E. V. Kolevatova, D. N. Nishnianidze
Supersymmetrical (SUSY) intertwining relations are generalized to the case of quantum Hamiltonians in Minkowski space. For intertwining operators (supercharges) of second order in…
New Methods for Two-Dimensional Schrödinger Equation: SUSY-separation of Variables and Shape Invariance
F. Cannata, M. V. Ioffe, D. N. Nishnianidze
Two new methods for investigation of two-dimensional quantum systems, whose Hamiltonians are not amenable to separation of variables, are proposed. 1)The first one - separa…
Intertwining relations of non-stationary Schrödinger operators
F. Cannata, M. Ioffe, G. Junker +1
General first- and higher-order intertwining relations between non-stationary one-dimensional Schrödinger operators are introduced. For the first-order case it is shown that the in…
Polynomial SUSY in Quantum Mechanics and Second Derivative Darboux Transformation
A. A. Andrianov, M. V. Ioffe, D. N. Nishnianidze
We give the classification of second-order polynomial SUSY Quantum Mechanics in one and two dimensions. The particular attention is paid to the irreducible supercharges which canno…
