Title:
Ultra-ocoldl Molecules for Quantum Chemistry and Molecular Assembly

Institution:
Harvard University

Department:
Chemistry and Chemical Biology

Description:
Ultracold molecular gases, at a temperature below of 0.00001 Kelvin, offer a range of exciting applications that are enabled by cooling the motion of molecules and controlling their internal quantum degrees of freedom such as vibrations and rotations. The large number of internal degrees of freedom complicates molecular cooling procedures and reduces their efficiency. We work toward a new approach to produce ultracold molecules by assembling them from ultracold atoms one at the time. We explore elementary chemical reactions of two diatomic molecules. With the near-zero kinetic energy of molecules, microscopic interactions between molecules dominate and determine the macroscopic behavior of the gas. These molecules, regarded as quantum 'legos', can be assembled together for quantum chemistry simulations.
