Dear Visitor,

Welcome to the ultracold atomic and molecular physics group in the Department of Physics and the James Franck Institute, at the University of Chicago. Here you will find a new and active research team exploring the quantum world at the lowest temperatures scientists can achieve, nearly a billionth of a degree Kelvin above absolute zero. Few sample images are shown in our Ultracold gallery. If you are interested in our research program or have any questions, please drop me a line, cchin @



2016 Midwestern Cold Atom Workshop will be held at the University of Chicago on October 28 and 29, 2016. The workshop will offer tutorials for young students interested in cold atom research on October 28 afternoon, and invited talks+poster session on October 29.


ARO/AFOSR MURI base period review meeting will be held at the University of Chicago from September 26 to 28, 2016.
