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…
