A note on the PT-invariant periodic potential V(x)=4 cos^2 x + 4 i V_0 sin 2x
Bikashkali Midya, Barnana Roy, Rajkumar Roychoudhury
It is shown that the PT symmetric Hamiltonian with the periodic potential V(x) = 4 cos^2 x + 4 i V_0 sin 2x can be mapped into a Hermitian Hamiltonian for , by a similarit…

Position Dependent Mass Schroedinger Equation and Isospectral Potentials : Intertwining Operator approach
Bikashkali Midya, Barnana Roy, Rajkumar Roychoudhury
Here we have studied first and second-order intertwining approach to generate isospectral partner potentials of position-dependent (effective) mass Schroedinger equation. The secon…
