Congratulations to Xiao Chai for a successful PhD defense! His PhD thesis is entitled “Magnetic dynamics in nonequilibrium spinor Bose-Einstein condensates”.
We have isolated and tracked very slowly moving individual atoms without the aid of laser cooling. Passive filtering enabled us to carefully select atoms whose three-dimensional velocity vector has a magnitude below v¯/20, where v¯ is the mean velocity of the ensemble. Using a novel photon correlation technique, we could follow the three-dimensional trajectory of single, slowly moving atoms for >1μs within a 25μm field of view, with no obvious limit to the tracking ability while simultaneously observing Rabi oscillations of these single emitters. Our results demonstrate the power and scalability of thermal ensembles for utilization in quantum memories, imaging, and other quantum information applications through bottom-up approaches.
A new paper from our group on the use of stimulated laser cooling to increase the brightness of chip-scale atomic beams for applications in quantum sensing and related technologies:
