Probing many-body states of interacting Rydberg atoms via fluorescence imaging. — •Henrik Hirzler, Tobias Wintermantel, Stephan Helmrich, Alda Arias, Graham Lochead, and Shannon Whitlock — Physikalisches Institut, Universität Heidelberg, Im Neuenheimer Feld 226, 69120 Heidelberg

Trapped ultracold atoms excited to Rydberg states provide a widely controllable platform for strongly-interacting many-body physics. We recently showed that the competition between driving fields, dissipation and interactions leads to several interesting dynamical regimes which exhibit scaling behavior [1]. We expect this is associated with the emergence of strong spatial correlations between the excited atoms. To probe these correlations we will optically down-pump the excited Rydberg atoms and then measure their fluorescence using a high-resolution imaging system, consisting of a high-NA objective lens and a high quantum efficiency camera. We will report progress towards spatially resolving correlations induced by Rydberg-Rydberg interactions down to single atom level.
