Just out in Nature - our paper on the first Bose-Einstein condensate of dipolar molecules, a gas of molecules cooled into the quantum regime. A big thank you to the entire NaCs team – past and present members – for the amazing work! Thank you to so many friends and colleagues for your support!! We are extremely grateful and excited to see what’s next!

I still remember how a vision, a crude 2D drawing of a molecular BEC on your whiteboard, and a tour of a defunct cleanroom (to become the lab) in Fall 2016 became an inspiration to join you on this journey. Congrats to you all on getting this amazing achievement!!

In collaboration with the Yu Lab at Columbia, we have created atomic tweezer arrays via holographic metasurfaces. Here a fluorescence image of Sr atoms in ~200 tweezer traps, spaced by ~3 um ⚛ 📸 😃 Congrats to the entire TweeSr team + Yu Lab on this beautiful achievement!!

Check out our latest preprint https://lnkd.in/eDuZwzTG - observation of Bose-Einstein condensation 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 rates by 4 orders of magnitude. We could not be more excited exploring this new quantum liquid... Thanks so much to the entire NaCs team for the amazing work, Niccolò Bigagli, Weijun YUAN, Siwei Zhang, Boris Bulatovic, Tijs Karman, and Ian Stevenson -- and former lab members Aden Lam and Claire Warner!!

Our latest work out as a preprint - https://lnkd.in/e679gS62 - we reinterpret the quantum states of molecules and transitions between them as a graph. This allows us to use fast graph-based search methods to detect laser cooling schemes in complex molecules in an automated way. We test our approach with C2, OH+, CN, YO, and CO2 and detect thousands of laser cooling schemes, including known ones from previous manual searches, but the vast majority of them so far unknown! Manual searches are much slower and suffer from human bias. Conceptually the change of perspective - viewing quantum states and their transitions as a graph - should be broadly applicable and might help finding quantum control schemes for other quantum systems with discrete spectra. We are extremely curious to see how this method can be applied to other use cases. Let us know your thoughts! Thank you, Anna Dawid, Niccolò Bigagli, Daniel Savin for this wonderful + fun + inspiring collaboration!! Columbia Quantum Initiative Columbia University
