Efficient single photon absorption by a recoiling atom — •Nils Trautmann and Gernot Alber — Institut für Angewandte Physik, Technische Universität Darmstadt,D- 64289, Germany

We investigate the impact of the center of mass motion on the attempt to efficiently excite a single two-level atom trapped close to the focal point of a parabolic mirror. We derive analytical expressions for the probability of exciting the atom and observables related to the momentum and position of the center of mass motion. By using these expressions, we are able to investigate the dynamics of the system far beyond the Lamb-Dicke regime. Furthermore, we propose a technique to overcome the limitations caused by the center of mass motion by using a time dependent trapping potential.
