Bose-Einstein condensate of dipolar molecules!

Dec 19, 2023

Our latest preprint is out - we report the first creation of a Bose-Einstein condensate of dipolar ground state molecules. We evaporatively cool a gas of NaCs molecules from 700 nK to 6 nK above absolute zero. At this point the molecular gas forms a Bose-Einstein condensate, the coldest molecular gas to date. The lifetime of the BEC is ~2 sec. This becomes possible with an enhanced collisional shielding method that suppresses loss by 4 orders of magnitude. Thanks so much to the entire NaCs team - past and present members - for all the amazing work on this monumental project!
