Rydberg excitations of cold atoms inside a hollow-core fiber — •Maria Langbecker, Mohammad Noaman, Chantal Voss, Maik Selch, Florian Stuhlmann, 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. Using this scheme, novel photonic states can be generated and studied with possible applications in quantum information and simulation.

This poster presents our experimental setup with laser cooled Rubidium atoms inside a hollow-core fiber. We explain the details of our transport procedure of the cold atoms into the fiber using an optical conveyor belt and show the first measurements of cold Rydberg excitations inside the fiber. In addition, we present the characterization of Kagomé-type hollow-core fibers whose properties allow for simultaneous atom guiding and two-photon Rydberg EIT excitation. Finally, we show our progress towards Rydberg quantum optics in a quasi-one-dimensional geometry.
