Mixtures of trapped atoms and ions form exciting new systems enabling the study of quantum chemistry, ultracold collisions and polaronic physics. Possible applications include sympathetic cooling of ions, ion-assisted detection of atoms and quantum simulation. In the ultracold regime the quantum dynamics of mixtures of fermionic atoms and ions and of fermion-phonon coupling may be studied [1]. We present our setup for realising a hybrid system of trapped Li atoms and Yb+ ions, where the large mass-ratio between ion and atom will allow us to reach the ultracold regime [2]. We discuss overlapping of magnetically trapped atoms with an ion crystal confined in the Paul trap and show first experimental results of atom-ion interactions and prospects for reaching the quantum regime.
