A Study of Quantum Many-Body Systems With Nearest And Next-to-Nearest Neighbour Long-Range Interactions
Meripeni Ezung, N. Gurappa, Avinash Khare +1
The scattering and bound states of the many-body systems, related to the short-range Dyson model, are studied. First, we show that the scattering states can be realized as coherent…

PT invariant Non-Hermitian Potentials with Real QES Eigenvalues
Avinash Khare, Bhabani Prasad Mandal
We show that at least the quasi-exactly solvable eigenvalues of the Schrödinger equation with the potential as well as the periodic potential $V(x) = (ζ…
