We investigate the entanglement dynamics of two spatially separated, identical two level atoms interacting via dipole forces and coupled to a common vacuum reservoir. We choose a general class of maximally entangled mixed states (MEMS) as initial states and study the entanglement dynamics. We observe all rank 4 MEMS exhibit entanglement sudden death followed by its revival. The relevance of the rank of the state and its change in the evolution is studied.
