A PT-Invariant Potential With Complex QES Eigenvalues
Avinash Khare, Bhabani Prasad Mandal
We show that the quasi-exactly solvable eigenvalues of the Schrödinger equation for the PT-invariant potential are complex conjugate pairs in case the p…

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…
