    "abstract": "The dynamics of entanglement and the phenomenon of entanglement sudden death\n(ESD) \\cite{yu} are discussed in bipartite systems, measured by Wootters\nConcurrence. Our calculation shows that ESD appears whenever the system is open\nor closed and is dependent on the initial condition. The relation of the\nevolution of entanglement and energy transfer between the system and its\nsurroundings is also studied.",
