Abstract
We consider two separated single mode dissipative cavities each containing a Λ-type three-level atom. The fields in cavities are both initially prepared in the coherent states, and the two Λ-type three-level atoms are initially prepared in the state \(|{\Psi }\rangle =\frac {1}{\sqrt {2}}(|ee\rangle +|gg\rangle )\). The result shows that, the entanglement between the two Λ-type three-level atoms decays to a steady value after a period of time of oscillations. And compared with entanglement of two-level atoms, the entanglement of the Λ-type three-level atoms is more stable and robust. We also show the impact of some parameters on the steady entanglement between the two atoms and the entanglement decreases most slowly for \(\varsigma \rightarrow 1\).
