Our setup for realising a hybrid system of ultra-cold atoms and ions is presented. This setup allows studying the quantum dynamics of mixtures of fermionic atoms and ions. Recent experiments have shown that the time-dependent trapping field of the ions can cause heating in hybrid atom-ion systems [1]. One way to mitigate this problem is to employ ion-atom combinations with a large mass ratio [2]. The highest convenient mass ratio - for species that still allow for straightforward laser cooling - is achieved by using the combination 171Yb+ and 6Li.
Combining ion trapping technology with ultra-cold lithium poses particular challenges that we address on this poster. We present numerical simulations showing that the s-wave limit may be reached in our setup, opening up the possibility of studying atom-ion Feshbach resonances [3] and show our first experimental results of atom-ion interactions.
