Dynamical protection of quantum steering and fidelity dynamics in double Jaynes-Cummings model
Koushik Mandal, Chitra Rangan, Shohini Ghose
We investigate the dynamics of Einstein-Podolsky-Rosen (EPR) steering in a double Jaynes-Cummings model, where two initially entangled spatially separated two-level atoms in two ca…

Pure and Mixed State Entanglement Dynamics in Tavis-Cummings Model with Squeezed Coherent Thermal States
Koushik Mandal, M. V. Satyanarayana
We investigate the entanglement dynamics of two atoms interacting with a single-mode cavity field within the Tavis-Cummings model in the presence of noise. The atoms are initially…

Entanglement dynamics in intensity-dependent double Jaynes-Cummings model for squeezed coherent thermal states
Koushik Mandal
In this paper, the entanglement dynamics of different subsystems such as atom-atom, atom-field and field-field with radiation field in squeezed coherent thermal states for the inte…
