Abstract

We give an overview of recent experiments on an ultracold Fermi-Bose quantum gas where the interspecies interaction can be tuned via magnetic Feshbach resonances. We first describe the various steps that have led to the observation of Feshbach resonances in the K-Rb system we investigate, and their accurate characterization. We then describe experiments in which Feshbach resonances are exploited to study interaction effects and to associate weakly bound KRb dimers.
