Sensitizing Non-Hermitian Hamiltonian for Study of Real Spectra : Controlled broken PT symmetry

preprint2020arXivOpen access

Abstract

We find that a broken PT-symmetry operator when interacts with suitable Hermitian operator, new system becomes completely un-broken PT symmetry. Further on varying the contribution of Hermiticity one can delay or control the broken PT-symmetry. Further beyond the critical contribution ,the broken PT symmetry becomes unbroken in nature. Analytical as well as numerical models have been presented.
