The conference will be jointly organized by the Institute of Theoretical Atomic, Molecular, and Optical Physics (ITAMP) at Harvard University, and the Institute of Science and Technology Austria (IST Austria). ITAMP has a two-decade history of organizing scientific workshops (https://www.cfa.harvard.edu/itamp/workshops.html), most of which took place in Cambridge MA (USA). CoQIPC - 2017 will be hosted by IST Austria in Klosterneuburg and therefore will represent one of the few exceptions taking place outside of ITAMP/Harvard. The aim of CoQIPC-2017 is to establish connections and networks by bringing together prominent scientists working with impurity problems in physics and chemistry, thereby fostering the exchange of ideas and collaboration between different areas. The main focus is to attract experimentalists and theorists working on polaron problems in ultracold quantum gases and solid state systems, molecules in superfluid helium nanodroplets, as well as on NV-centers in diamond.
