In the framework of perturbation theory the reality of the perturbed eigenvalues of a class of PT-symmetric Hamiltonians is proved using stability techniques. We apply this method to PT-symmetric unperturbed Hamiltonians perturbed by PT-symmetric additional interactions.

Abstract
In the framework of perturbation theory the reality of the perturbed eigenvalues of a class of PT-symmetric Hamiltonians is proved using stability techniques. We apply this method to PT-symmetric unperturbed Hamiltonians perturbed by PT-symmetric additional interactions.File in questo prodotto:
