Optical production of ultracold polar molecules — •Dave de Mille — Dept of Physics, Yale University, Sloane Physics Lab, New Haven, Connecticut 06520, USA

We have recently demonstrated the production of ultracold, polar RbCs molecules in their vibronic ground state, via a multi-step optical ”assembly” process beginning from laser-cooled atoms. The resulting sample has translational temperature T 100 uK and a narrow distribution of rotational states. An extension of our techniques, now underway, should allow study of a trapped sample of absolute ground-state RbCs molecules, opening the possibility to study an ultracold gas in the regime of strong dipolar interactions.
