Periodic Quasi - Exactly Solvable Models
S. Sree Ranjani, A. K. Kapoor, P. K. Panigrahi
Various quasi-exact solvability conditions, involving the parameters of the periodic associated Lam{é} potential, are shown to emerge naturally in the quantum Hamilton-Jacobi appro…

Quantum Hamilton-Jacobi analysis of PT symmetric Hamiltonians
S. Sree Ranjani, A. K. Kapoor, Prasanta K. Panigrahi
We apply the quantum Hamilton-Jacobi formalism, naturally defined in the complex domain, to a number of complex Hamiltonians, characterized by discrete parity and time reversal (PT…
