Quantum phase transitions and entanglement entropy in a non-Hermitian Jaynes-Cummings model
Gargi Das, Aritra Ghosh, Bhabani Prasad Mandal
In this paper, we describe some interesting properties of a non-Hermitian Jaynes-Cummings model. For this particular model, it is known that the Hilbert space can be described by i…

Dirac-isotonic oscillators in (1 + 1) and (2 + 1) dimensions
Aritra Ghosh, Bhabani Prasad Mandal
We discuss the Dirac oscillator in and dimensions and generalize it in the spirit of the isotonic oscillator using supersymmetric quantum mechanics. In dime…
