Pseudo-Hermitian versus Hermitian position-dependent-mass Hamiltonians in a perturbative framework
B. Bagchi, C. Quesne, R. Roychoudhury
We formulate a systematic algorithm for constructing a whole class of Hermitian position-dependent-mass Hamiltonians which, to lowest order of perturbation theory, allow a descript…

Pseudo-Hermiticity and some consequences of a generalized quantum condition
B. Bagchi, C. Quesne, R. Roychoudhury
We exploit the hidden symmetry structure of a recently proposed non-Hermitian Hamiltonian and of its Hermitian equivalent one. This sheds new light on the pseudo-Hermitian characte…

New approach to (quasi)-exactly solvable Schrodinger equations with a position-dependent effective mass
B. Bagchi, P. Gorain, C. Quesne +1
By using the point canonical transformation approach in a manner distinct from previous ones, we generate some new exactly solvable or quasi-exactly solvable potentials for the one…
