Character of Locally Inequivalent Classes of States and Entropy of Entanglement
Indrani Chattopadhyay, Debasis Sarkar
In this letter we have established the physical character of pure bipartite states with the same amount of entanglement in the same Schmidt rank that either they are local unitaril…
A generalized non-Hermitian oscillator Hamiltonian, N-fold supersymmetry and position-dependent mass models
Bijan Bagchi, Toshiaki Tanaka
A generalized non-Hermitian oscillator Hamiltonian is proposed that consists of additional linear terms which break PT-symmetry explicitly. The model is put into an equivalent Herm…
A complex periodic QES potential and exceptional points
B. Bagchi, C. Quesne, R. Roychoudhury
We show that the complex -symmetric periodic potential , where is real and is a positive integer, is quasi-exactly solvable. For…
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…
Position-dependent mass models and their nonlinear characterization
B. Bagchi
We consider the specific models of Zhu-Kroemer and BenDaniel-Duke in a sech-mass background and point out interesting correspondences with the stationary 1-soliton and 2-soli…
New supersymmetric partners for the associated Lame potentials
David J Fernandez C, Asish Ganguly
We obtain exact solutions of the one-dimensional Schrodinger equation for some families of associated Lame potentials with arbitrary energy through a suitable ansatz, which may be…
