Millisecond Dynamics of Ultracold Rydberg Gases — •Tobias Weber, Thomas Niederprüm, Torsten Manthey, Giovanni Barontini, Vera Guarrera, and Herwig Ott — TU Kaiserslautern

We observe ultracold atoms continuously coupled to Rydberg states on a timescale exceeding the vastly investigated so called frozen Rydberg regime. A scanning electron microscope technique is exploited to prepare distributions of mesoscopic ensemples with dipole-dipole interactions induced by resonant and off-resonant excitation. Characterisations of correlations between Rydberg atoms and of ionization processes are derived from the analysis of the ion signal.
