Reconstructing the nucleon-nucleon potential by a new coupled-channel inversion method

Andrey Pupasov, Boris F. Samsonov, Jean-Marc Sparenberg +1

A second-order supersymmetric transformation is presented, for the two-channel Schrödinger equation with equal thresholds. It adds a Breit-Wigner term to the mixing parameter, with…

Eigenphase preserving two-channel SUSY transformations

Andrey M Pupasov, Boris F Samsonov, Jean-Marc Sparenberg +1

We propose a new kind of supersymmetric (SUSY) transformation in the case of the two-channel scattering problem with equal thresholds, for partial waves of the same parity. This tw…

Spectral properties of non-conservative multichannel SUSY partners of the zero potential

Andrey M Pupasov, Boris F Samsonov, Jean-Marc Sparenberg

Spectral properties of a coupled potential model obtained with the help of a single non-conservative supersymmetric (SUSY) transformation starting from a system of …

Coupling between scattering channels with SUSY transformations for equal thresholds

Andrey M Pupasov, Boris F Samsonov, Jean-Marc Sparenberg +1

Supersymmetric (SUSY) transformations of the multi-channel Schrödinger equation with equal thresholds and arbitrary partial waves in all channels are studied. The structures of the…

Exactly-solvable coupled-channel potential models of atom-atom magnetic Feshbach resonances from supersymmetric quantum mechanics

Andrey M. Pupasov, Boris F. Samsonov, Jean-Marc Sparenberg

Starting from a system of radial Schrödinger equations with a vanishing potential and finite threshold differences between the channels, a coupled exactly-solvable…

Exact propagators for SUSY partners

Andrey M. Pupasov, Boris F. Samsonov, Uwe Guenther

Pairs of SUSY partner Hamiltonians are studied which are interrelated by usual (linear) or polynomial supersymmetry. Assuming the model of one of the Hamiltonians as exactly solvab…
