Professor, Kang-Kuen Ni / Title: Bringing together Chemistry and Physics with Ultracold Molecules

Ms. Ni is a Morris Kahn Associate Professor of Chemistry, Chemical Biology and Physics  Harvard University. 

Abstract: Advances in quantum manipulation of molecules bring unique opportunities, including the use of molecules to search for new physics, harnessing molecular resources for quantum engineering, and exploring chemical reactions in the ultra-low temperature regime. In this talk, I focus on the latter topic where we work toward a detailed microscopic picture of molecules transforming from one species to another and reveal several surprises along the way. By preparing quantum-state-selected KRb molecules at a temperature of 500 nK, we observed reactions proceeding through a long-lived intermediate, which provides a handle to steer with light the reaction pathway away from its natural course. Despite the long lifetime that might allow thermalization, our measurements indicate that ergodicity does not hold for all degrees of freedom.
