Abstract
We analyze entanglement dynamics and transfer in a system composed of two
initially correlated two-level atoms, in which each atom is coupled with another
atom interacting with its own reservoir. Considering atomic dipole-dipole
interactions, the results show that dipole-dipole interactions restrain the
entanglement birth of the reservoirs, and a parametric region of dipole-dipole
interaction strength exists in which the maximal entanglement of two initially
uncorrelated atoms is reduced. The transfer of entanglement shows obvious different
behaviors in two initial Bell-like states.
