Setup for studying Li-Yb+ mixtures in the quantum regime — •Henning Fürst¹, Jannis Joger¹, Norman Ewald¹, Thomas Feldker¹, Thomas Secker², and René Gerritsma¹ — ¹Institute of Physics, University of Amsterdam, Netherlands — ²Institute for Coherence and Quantum Technology, TU Eindhoven, Netherlands

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.
