Towards nonlinear optics with cold Rydberg atoms inside a hollow-core fiber — •Maria Langbecker, Mohammad Noaman, and Patrick Windpassinger — Universität Mainz, QUANTUM, Institut für Physik, Staudingerweg 7, 55128 Mainz, Germany

Cold atoms inside hollow-core fibers present a promising system to study strongly nonlinear light-matter interaction. Combined with the long range Rydberg interaction and the possibility to tune the interaction strength through an EIT process, a corresponding experimental setup should allow for the generation of a strong and tunable effective photon-photon interaction [1]. As a consequence, novel states light can be generated and studied.

We present an experimental setup where laser cooled Rubidium atoms are transported into a hollow-core Kagomé fiber. The fiber properties allow for simultaneous atom trapping and Rydberg-EIT excitation and we discuss the progress towards this first step for nonlinear Rydberg physics in a quasi-one-dimensional geometry.
