CPT-conserved effective mass Hamiltonians through first and higher order charge operator C in a supersymmetric framework
B. Bagchi, A. Banerjee, A. Ganguly
This paper examines the features of a generalized position-dependent mass Hamiltonian in a supersymmetric framework in which the constraints of pseudo-Hermiticity and CPT are natur…
Lie-algebraic structure of 2D harmonic oscillator with non-separable complex coupling
Asish Ganguly, Suman De
An attempt had been made to get algebraic structure of 2D complex harmonic oscillator.
Shape-invariant quantum Hamiltonian with position-dependent effective mass through second order supersymmetry
A. Ganguly, L. M. Nieto
Second order supersymmetric approach is taken to the system describing motion of a quantum particle in a potential endowed with position-dependent effective mass. It is shown that…
A new effective mass Hamiltonian and associated Lame equation: bound states
A. Ganguly, M. V. Ioffe, L. M. Nieto
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 ef…
Exactly solvable associated Lame potentials and supersymmetric transformations
David J. Fernandez C., Asish Ganguly
A systematic procedure to derive exact solutions of the associated Lame equation for an arbitrary value of the energy is presented. Supersymmetric transformations in which the seed…
A study of the bound states for square potential wells with position-dependent mass
A. Ganguly, S. Kuru, J. Negro +1
A square potential well with position-dependent mass is studied for bound states. Applying appropriate matching conditions, a transcendental equation is derived for the energy eige…
