Rydberg excitations of cold atoms inside a hollow-core fiber — •Parvez Islam, Maria Langbecker, Mohammad Noaman, Chantal Voss, Ronja Wirtz, Wei Li, and Patrick Windpassinger — 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.

We present our measurements of cold Rydberg excitations inside a hollow-core fiber to characterize the Rydberg atom-fiber interaction by using electromagnetically induced transparency (EIT) signals [1]. A time resolved detection method was implemented to distinguish between EIT excitation and atom loss. In a separate setup at room temperature, we also investigate the influence of different types of fiber coatings and geometries on Rydberg EIT. Here we observe signals for levels up to the 85D state.
