Towards Rydberg polariton dynamics with cold atoms in quasi 1D geometries — •Mohammad Noaman, Maria Langbecker, and Patrick Windpassinger — QUANTUM, Institut für Physik, Johannes Gutenberg-Universität Mainz, Staudingerweg 7, 55128 Mainz, Germany

Cold atoms inside hollow-core fibers present a promising candidate to study strongly coupled light-matter systems. Combined with the long range Rydberg interaction which is controlled through an EIT process, a corresponding experimental setup should allow for the generation of a strong and tunable polariton interaction. Due to dipole blockade, polaritons are restricted to a quasi one dimensional structure. Using this scheme, novel photonic states, eg. crystallization of photons, can be observed with possible applications in quantum information and simulation. This talk will review the current status of our experimental setup where laser cooled Rubidium atoms are transported into a hollow-core fiber. We present the first measurements of Rydberg EIT of the optical molasses in front of the fiber and discuss the progress towards Rydberg physics in a quasi-one-dimensional geometry.
