DESCRIPTION:Dr. Michael Koehl\nIn recent years\, ultracold atoms have emer
 ged as an exceptionally well controllable experimental system to investiga
 te fundamental physics\, ranging from quantum information science to simul
 ations of condensed matter models.\nHere we go one step further and explor
 e how cold atoms can be combined with other quantum systems to create new 
 quantum hybrids with tailored properties. Coupling atomic quantum many-bod
 y states to an independently controllable single-particle quantum system g
 ives access to a wealth of novel physics and to completely new detection a
 nd manipulation techniques.\nIn the talk\, we will report on recent experi
 ments in which we have for the first time deterministically placed a singl
 e ion into an atomic Bose Einstein condensate [1]. A trapped ion\, which c
 urrently constitutes the most pristine single particle quantum system\, ca
 n be steered with nanometer precision within the atomic cloud and can be o
 bserved and manipulated at the level of a single particle. In the created 
 single-particle/many-body composite quantum system we show sympathetic coo
 ling of the ion\, observe chemical reactions of single particles in situ\,
  and explore non-equilibrium dynamics. An outlook into possible future dev
 elopments will be given.\n\n[1] C. Zipkes\, S. Palzer\, C. Sias\, M. Köhl
