A sodium potassium mixture experiment for simulating polaron physics — •Jan Kilinc, Lilo Höcker, Lorenz Hahn, Joris Hoffmann, Maurus Hans, Helmut Strobel, and Markus Oberthaler — Kirchhoff Institut für Physik, Heidelberg, Deutschland

The motion of quantum impurities in a Bose-Einstein condensate (BEC) is an exemplary many-body phenomenon and a theoretical challenge especially in the regime of strong interactions between the impurities and the BEC. In the experiment such a Polaron problem can be studied using an atomic mixture, where one species realizes the impurity, while the BEC is realized with the other species. The interaction can be controlled by sizeable inter-species Feshbach resonances between sodium and potassium. In this poster, we present the current status of our sodium potassium experiment.
