Abstract: (3180 Views)
In this paper we consider the interaction between two Λ–Type three–level atoms and a single-mode coherent cavity field with intensity-dependent coupling. After obtaining the explicit form of the atom-field state vector, the entanglement between the two atoms and the applied field is examined by using the concurrence measure. Also, the effects of the detuning parameter as well as initial mean photon number on the entanglement are discussed. The results show that, the atom-field entanglement can be sensitively controlled via these parameters.
Keywords: Detuning parameter, Entanglement, Intensity-dependent coupling, Concurrence, Jaynes-Cummings model
