*Title: *Ultracold Molecules in Optical Tweezers
*Abstract: *I will describe some of our recent work in direct laser cooling
and trapping of CaF molecules. We have developed new techniques to
laser-cool optically trapped molecules well below the Doppler limit, and
have demonstrated a vastly improved detection scheme that makes possible
non-destructive high-fidelity imaging of trapped single molecules. Very
recently, using these methods, we have loaded and imaged single CaF
molecules trapped in optical tweezers. In the future, by rearranging these
traps, defect-free tweezer arrays of ultracold molecules can be created,
providing a bottom-up approach in assembling interacting many-body systems
molecule-by-molecule. This approach is also extendable to many other
molecules, including larger polyatomic ones, which could be ideally suited
for molecular qubits or for searches of beyond-Standard-Model physics.
