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! nature.com/articles/s4158…

Our paper on self-bound droplets in a BEC of dipolar molecules is out in Nature! The droplets reach densities 100x higher than in the BEC, entering the strongly interacting regime. Opening the door for new phases, supersolidity and dipolar crystals.

Excellent coverage by Optica OPN of our metasurface atomic tweezer work, with lots of technical details accessibly explained

New paper out in Nature! Together with the Yu Lab at Columbia, we realize single-atom trapping using metasurface optical tweezers and show a path toward atomic arrays with >100,000 traps. Huge thanks to the entire team @ TweeSr Lab and Yu Lab!

Check out our preprint - first observation of droplets in Bose-Einstein condensates of ultracold molecules!! Droplets appear when increasing dipolar interactions. Molecule density reaches 100x the density in the BEC. Possibly a quantum liquid or a crystal?arxiv.org/abs/2507.15208
