"Advancing optical lattice clocks: From cryogenic silicon cavities to superexchange interactions"

Optical lattice clocks provide a testbed for a wide range of science spanning from studies of fundamental physics to probing novel many-body states. To improve clock precision, probing increasingly many atoms for the longest coherence times affordable is necessary. In this talk, I will summarize recent work at JILA  coherently interrogating atoms trapped in a three-dimensional optical lattice via an ultrastable laser to understand and advance clock precision. With a Fermi-degenerate gas of strontium atoms, we perform seconds long clock spectroscopy to probe Fermi- Hubbard physics and thus understand the effects of  superexchange interactions on our coherence time. This work provides a groundwork for using optical lattice clocks to probe quantum magnetism and spin
entanglement.
