Hamiltonians with position-dependent mass, deformations and supersymmetry
C. Quesne, B. Bagchi, A. Banerjee +1
A new method for generating exactly solvable Schrödinger equations with a position-dependent mass is proposed. It is based on a relation with some deformed Schrödinger equations, w…
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…
First-order intertwining operators and position-dependent mass Schrodinger equations in d dimensions
C. Quesne
The problem of d-dimensional Schrodinger equations with a position-dependent mass is analyzed in the framework of first-order intertwining operators. With the pair (H, H_1) of inte…
PT-supersymmetric partner of a short-range square well
C. Quesne, B. Bagchi, S. Mallik +3
In a box of size , a spatially antisymmetric square-well potential of a purely imaginary strength and size is interpreted as an initial element of the SUSY hi…
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…
