Abstract: (6504 Views)
In this paper, a model for studying the interaction between a motional three-level atom (in configuration) and two-mode field injected simultaneously in a bichromatic cavity is presented. Under particular initial conditions, which may be prepared for the atom and the field, the time evolution of state vector of the entire system is analytically obtained. Then, dynamics of entanglement is evaluated by using the von Neumann reduced entropy. The numerical results show that, the duration and the maximum amount of the entanglement can be suitably tuned by selecting the proper field-mode structure parameter p.
Keywords: Jaynes-Cummings model, Moving three-level atom, Bimodal field, Parametric down conversion, Quantum entanglement.
