Construction of maximally non-Hermitian potentials under unbroken PT-symmetry constraint
Original language description
A family of discrete Schrödinger equations with imaginary and maximally non-Hermitian multiparametric potentials V(x, A, B, ...) is studied. In the domain of unitarity-compatible parameters D (known as the domain of spontaneously unbroken PT-symmetry) the reality of all of the bound-state energies E-n(A, B, ...) survives up to the maximally non-Hermitian 'exceptional-point' extreme with parameters A((EP)), B-(EP), ... The computer-assisted proof of existence and the symbolic-manipulation localization of such a spectral-degeneracy limit are sampled showing that their complexity grows quickly with the number of parameters.
