Exactly solvable models with PT-symmetry and with an asymmetric coupling of channels

Quantum Physics 2009-11-11 v1

Abstract

Bound states generated by K coupled PT-symmetric square wells are studied in a series of models where the Hamiltonians are assumed RR-pseudo-Hermitian and R2R^2-symmetric. Specific rotation-like generalized parities RR are considered such that RN=IR^N=I at some integers N. We show that and how our assumptions make the models exactly solvable and quasi-Hermitian. This means that they possess the real spectra as well as the standard probabilistic interpretation.
