Dissipative dynamics of strongly interacting driven Rydberg gases — •Jana Bender, Patrick Mischke, Carsten Lippe, Tanita Klas, Erik Bernhart, Thomas Niederprüm, and Herwig Ott — Department of Physics and research center OPTIMAS, Technische Universität Kaiserslautern, Germany

By continuously driving open Rydberg many-body systems, we investigate the interplay between Rydberg blockade and facilitation. We discuss the dynamics and steady states of a system of mesoscopic Rydberg blockaded clouds loaded into a one-dimensional optical lattice with a lattice constant tailored to match the facilitation distance of the 70S Rydberg state. Each cloud acts as an effective two-level system with an asymmetric excitation and deexcitation rate, a so-called superatom. The chain of superatoms created in the lattice allows to study dissipative Ising-like spin models.

Experimentally, we examine the correlations of excitations within these superatoms. The analysis of temporal correlations gives evidence of sub-poissonian behaviour in the resonantly driven system due to the Rydberg blockade.
