摘要

@@ We study the entanglement dynamics of two atoms with initial tripartite entangled W-like state in the Tavis-Cummings model.We find that the entanglement evolvement is sensitive not only to the entanglement degree of the initial state but also to the concrete form of the initial state.The so-called sudden death effect occurs only for some initial states.
