Nonlinear Dynamics of a position-dependent mass driven Duffing-type oscillator
Bijan Bagchi, Supratim Das, Samiran Ghosh +1
We examine some nontrivial consequences that emerge from interpreting a position-dependent mass (PDM) driven Duffing oscillator in the presence of a quartic potential. The propagat…
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…
A generalized non-Hermitian Pais-Uhlenbeck quantum Hamiltonian, its Hermitian equivalence and position-dependent mass correspondence
B. Bagchi, A. Ghose Choudhury, Partha Guha
We explore the Jacobi Last Multiplier as a means for deriving the Lagrangian of a fourth-order differential equation. In particular we consider the classical problem of the Pais-Uh…
Competing PT potentials and re-entrant PT symmetric phase for a particle in a box
Yogesh N. Joglekar, Bijan Bagchi
We investigate the effects of competition between two complex, -symmetric potentials on the -symmetric phase of a "particle in a box". These potentials,…
