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…
SUSY Quantum Mechanics with Complex Superpotentials and Real Energy Spectra
A. A. Andrianov, F. Cannata, J. -P. Dedonder +1
We extend the standard intertwining relations used in Supersymmetrical (SUSY) Quantum Mechanics which involve real superpotentials to complex superpotentials. This allows to deal w…
Schrödinger operators with complex potential but real spectrum
Francesco Cannata, Georg Junker, Johannes Trost
Several aspects of complex-valued potentials generating a real and positive spectrum are discussed. In particular, we construct complex-valued potentials whose corresponding Schröd…
