Spectral singularity and non-Hermitian PT-symmetric extension of $A_{N - 1}$ type Calogero model without confining potential

Bhabani Prasad Mandal, Ananya Ghatak

We consider non-Hermitian PT-symmetric deformation of $A_{N - 1}$ type Calogero model without confining potential to investigate the possible existence of spectral singularity. By co…

Spectral singularity and deep multiple minima in the reflectivity in non-Hermitian (complex) Ginocchio potential

Ananya Ghatak, Bhabani Prasad Mandal, Zafar Ahmed

We bring out the existence of at most one spectral singularity (SS) and deep multiple minima in the reflectivity of the non-Hermitian (complex) Ginocchio potential. We find a param…

Entangled Quantum State Discrimination using Pseudo-Hermitian System

Ananya Ghatak, Bhabani Prasad Mandal

We demonstrate how to discriminate two non-orthogonal, entangled quantum state which are slightly different from each other by using pseudo-Hermitian system. The positive definite…
