Dynamic Entanglement of Atomic Motion — •Mark Rodenberger and Matthias Freyberger — Institut für Quantenphysik, Universität Ulm, D-89069 Ulm, Germany

We analyze continuous bipartite entanglement of motional atomic degrees of freedom. The model consists of two atoms scattered on a quantized electric field one after the other, i.e. they never directly interact. A certain velocity regime allows for a complete analytical treatment of the corresponding dynamics. The resulting density operator is examined by means of various entanglement criteria and measures. In particular, we are interested in the scaling of entanglement with classical parameters like the initial momentum.
