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…
Feshbach projection-operator formalism to resonance scattering on Bargmann-type potentials
Varvara V. Shamshutdinova, Konstantin N. Pichugin, Ingrid Rotter +1
The projection-operator formalism of Feshbach is applied to resonance scattering in a single-channel case. The method is based on the division of the full function space into two s…
The Naimark dilated PT-symmetric brachistochrone
Uwe Guenther, Boris F. Samsonov
The quantum mechanical brachistochrone system with PT-symmetric Hamiltonian is Naimark dilated and reinterpreted as subsystem of a Hermitian system in a higher-dimensional Hilbert…
