Seminarium KMMF "Teoria Dwoistości"

Atomic samples cooled to quantum degeneracy offer exciting opportunities for quantum simulations and precision measurements. Since the first realization of the Bose-Einstein condensate in a weakly interacting gas, many new systems emerged with different types of interactions. In particular, creation of hybrid ion-atom systems enabled the studies of impurity physics in the strongly interacting regime. In this talk, I will describe the basic features of few- and man-body problems involving mixtures of ions and atoms and then discuss recent breakthrough experiments studying charge transport in a cold gas and demonstrating control over the ion-atom interaction strength by means of Feshbach resonances.
