Single-atom electromagnetically induced transparency in a strongly coupled atom-cavity system — •Haytham Chibani, Christoph Hamsen, Ingmari Tietje, Paul A. Altin, Tatjana Wilk, and Gerhard Rempe — Max-Planck-Institute of Quantum Optics, Hans-Kopfermann-Str. 1, 85748 Garching, Germany

The realization of controllable nonlinearities at the level of single quanta of matter and light is one of the main goals of quantum optics. A recent theoretical study [1] predicted that photon statistics of an incoming laser beam could be coherently controlled by means of a system which merges single-atom cavity quantum electrodynamics (QED) with electromagnetically induced transparency (EIT). Towards achieving this goal, we report on the latest experimental results obtained with our atom-cavity apparatus which has at its heart a single ⁸⁷Rb atom strongly coupled to a cavity mode. We present transmission measurements for a single atom showing for the first time both the EIT window and the normal mode structure which is the signature of a strongly coupled cavity QED system.
