A study of the bound states for square potential wells with position-dependent mass
TL;DR: In this paper, a potential well with position-dependent mass was studied for bound states and a transcendental equation was derived for the energy eigenvalues, and the variation of the energy of the bound states were calculated as a function of the well width and mass.
Journal ArticleDOI
Shape-invariant quantum Hamiltonian with position-dependent effective mass through second-order supersymmetry
Asish Ganguly,Luis Miguel Nieto +1 more
TL;DR: In this paper, a second-order supersymmetric approach is taken to the system describing motion of a quantum particle in a potential endowed with position-dependent effective mass, and the intertwining relations between secondorder partner Hamiltonians may be exploited to obtain a simple shape-invariant condition.
Journal ArticleDOI
Higher derivative supersymmetry, a modified Crum-Darboux transformation and coherent state
TL;DR: In this article, a modified form of the well-known Crum-Darboux transformation is proposed for generating a new pair of isospectral potentials, and the interesting problem of constructing coherent states for such factorizable operators is considered.

A new effective mass Hamiltonian and associated Lamé equation: bound states
TL;DR: In this paper, a new quantum model with rational functions for the potential and effective mass is proposed in a stretchable region outside which both are constant, starting from a generalized effective mass kinetic energy operator the matching and boundary conditions for the envelope wavefunctions are derived.
