Overlapping BECs of Na and Cs

Check out our latest paper - first dual Bose-Einstein condensates of sodium and cesium. Two overlapping superfluids and exciting conditions to make very cold clouds of NaCs ground state molecules. Congrats to the entire NaCs Lab team for this great achievement! Link to the preprint: arxiv:2106.01334

Triangular Lattice from Metasurface

We got our first image of a triangular lattice pattern from a metasurface! It is the first step towards integrating this novel nanophotonic platform into an AMO experiment. We are looking forward to trapping atoms using it in the near future! Thank you Xiaoyan from Prof. Nanfang Yu’s group for providing the metasurfaces.

Array of 900 Laser Traps

We produced an optical tweezer array with 30x30 traps! It is generated by two crossed acousto-optic deflectors driven with a comb of radiofrequency tones. The trap spacing is about 5 micrometers. Congrats to the entire TweeSr lab!

First Cesium BEC

First Cesium Bose-Einstein condensate in the NaCs lab! Less than a year after the Sodium BEC, we have made the Cesium BECs in the same apparatus, lowering the temperature of the coldest spot in NYC by another factor of 10 to about 10 nanokelvin above absolute zero.
