In recent years, ultracold atoms have emerged as an exceptionally well controllable experimental system to investigate fundamental physics, ranging from quantum information science to simulations of condensed matter models.
Here we go one step further and explore how cold atoms can be combined with other quantum systems to create new quantum hybrids with tailored properties. Coupling atomic quantum many-body states to an independently controllable single-particle quantum system gives access to a wealth of novel physics and to completely new detection and manipulation techniques.
In the talk, we will report on recent experiments in which we have for the first time deterministically placed a single ion into an atomic Bose Einstein condensate [1]. A trapped ion, which currently constitutes the most pristine single particle quantum system, can be steered with nanometer precision within the atomic cloud and can be observed and manipulated at the level of a single particle. In the created single-particle/many-body composite quantum system we show sympathetic cooling of the ion, observe chemical reactions of single particles in situ, and explore non-equilibrium dynamics. An outlook into possible future developments will be given.
