摘要

It is considered that three identical two-level atoms are separately trapped in three coupled single-mode optical cavities,and each atom resonantly interacts with cavity via a one-photon transition.The tripartite entanglement dynamics among atoms is studied.The influence of cavity-cavity coupling constant on the tripartite entanglement among atoms is discussed.The results obtained using the numerical method show that the tripartite entanglement among atoms has a nonlinear relation with the cavity-cavity coupling coefficient.On the other hand,the three-body entanglement is the result of the coherent superposition of the two-body entanglements.
