PT-symmetric model with an interplay between kinematical and dynamical non-localities

Quantum Physics 2015-04-24 v3

Abstract

A new family of non-Hermitian PT-symmetric quantum models is proposed in which the Hamiltonians H=T+VH=T+V are finite-dimensional and in which the dynamical-input potential VV is multi-parametric and non-local. The choice is supported by the exact solvability of Schr\"{o}dinger equation and by the well known fact that in PT-symmetric models a non-locality is already present due to the generic kinematical non-diagonality of the Hermitizing metrics Θ\Theta. For a subfamily of our HHs, also {\em all\,} of the eligible metrics Θ\Theta appear obtainable in closed form.
