Collège de France Jean Dalibard Chaire Atomes et Rayonnement Année 2023-2024 Séminaire - Cheng Chin : Bose Enhanced Chemical Reactions in Atom-Molecule Bose-Einstein Condensates Cheng Chin James Franck institute, Enrico Fermi institute, Department of Physics, University of Chicago, USA Résumé Are chemical reactions described by new principles when atoms and molecules are cooled to the ground state? In this talk, I will describe the observation of coherent reactions between Bose condensed atoms and molecules at 10 nano-Kelvins. Cheng Chin Cheng Chin obtained his Ph.D. in Physics from Stanford University and has been a professor in Physics at the University of Chicago since 2005. He won the APS I.I. Rabi Prize (2011) and the Bose-Einstein Condensation Award (2017). His research covers Laser cooling and trapping, Bose-Einstein condensation and degenerate Fermi gas, Feshbach resonance, quantum simulation and quantum control.
