Light propagation in strongly interacting Rydberg gases — •Martin Gärttner and Jörg Evers — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg

Electromagnetically induced transparency in Rydberg gases has proven a valuable tool for applications in non-linear optics. Recently, single photons and other non-classical states of light have been produced using light propagation through strongly interacting Rydberg gases. We present a model describing the propagation of a weak probe beam in the presence of a strong coupling beam, coupling to a strongly interacting Rydberg level. Our model is based on the rate equation ansatz [1,2] and includes the attenuation of the probe beam. We test our model by comparing to experimental results of the group of M. Weidemüller [3] covering a large range of atomic densities and to other state of the art models. We find that all properties but the excitation statistics are described well by the rate equation model, indicating that quantum correlations in the light field should be taken into account.
