In this most recent paper, we show how to scale tweezer arrays to 320 sites, while maintaining atomic coherence at the half-minute-scale. This allows us to reach excellent stability through frequency self-comparisons in the array, as well as to characterize the single-particle coherence in the array through correlation measurements.
We've recently posted our new paper in which we benchmark the performance of optical tweezer arrays of strontium for optical atomic clocks and quantum state control!
We recently posted our first paper on arxiv! We demonstrate tweezer-trapping, single-particle imaging, light-shift free spectroscopy, and three-dimensional ground-state cooling of strontium!
