摘要：
In the present work we study the entanglement dynamics between two atoms when one of them, considered as having either two or three levels, is left to interact with a single mode of a high-Q cavity through two-photon processes. Making use of the negativity, we show the necessary conditions for these systems to exhibit the sudden death phenomena.
