A Magic Balance in Optical Lattice Clocks

Local interactions in the same lattice pull clock frequency negative while interactions between atoms on neighboring lattice sites pull clock frequency positive. By adjusting the atomic confinement, or tightness, of the lattice, researchers can balance these two counteracting forces to increase clock sensitivity.

Nelson joined the lab in September 2022 as a Humboldt postdoctoral fellow. He obtained his Ph.D. from the Bloch group at LMU in Munich, where he worked on ultracold ytterbium quantum gases in optical lattices. For his thesis work, he explored how the clock state of ytterbium can be employed for the simulation of interesting multiorbital models from solid-state physics.

I am a VATAT postdoctoral research fellow working on high-precision mid-IR spectroscopy of buffer gas cooled fullerenes. I earned my PhD in the Fleischer lab at Tel-Aviv University on ultrafast rotational echo spectroscopy and coherent molecular dynamics of gas phase ensembles.
