Atomic & Molecular Physics

Our recent manuscript — "Microscopic control and detection of ultracold strontium in optical tweezer arrays" — was published in PRX (Phys. Rev. X 8, 041054). See also the viewpoint from Antoine Browaeys (Viewpoint: Alkaline Atoms Held with Optical Tweezers) and the JILA highlight!

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!

Microwaves report on the direction of a magnetic field!  Our work on self-calibrated atomic vector magnetometry has been published in Phys. Rev. Lett.  We show that a microwave polarization ellipse can be mapped with atomic transitions, and can serve as a useful three-dimensional reference.  Our next step is to translate this idea to atomic vapor cells to make an atomic vector magnetometer that can calibrate itself at any time.
