Second-generation apparatus for Ryberg-atoms in an ultracold gas — •Huan Nguyen, Michael Schlagmüller, Stephan Jennewein, Christoph Tresp, Robert Löw, Sebastian Hofferberth, and Tilman Pfau — 5. Phys. Institut, Universität Stuttgart

The giant size and large polarizibility of Rydberg-atoms, resulting in strong long-range Rydberg-Rydberg interactions, make them ideal for studying many-body cooperative effects. In particular, the investigation of dense, ultracold Rydberg-gases in a magnetic trap has opened the door to novel effects such as Rydberg-molecules. Here, we present a new experimental apparatus for the creation and dynamic study of Rydberg-atoms in dense, ultra-cold atomic ensembles. Specific design goals of this new setup are single ion-detection capability, sub-micron optical resolution, and high flexibility in creating both magnetic and optical trapping potentials. We discuss how these different aspects are combined in a single, compact experimental realization.
