- I lead our effort to utilize a state-of-the-art ultrastable laser to attain record clock stability with two Strontium optical atomic clocks. Clock stability is vital to applications in precision timekeeping and fundamental physics. I built the cryogenic silicon reference cavity setup and used it to stabilize our spectroscopy laser to a sub-10 mHz linewidth. I then performed clock spectroscopy with two independent atomic ensembles and measured their relative noise. Using the data and a detailed noise budget, I was able to infer the individual stability of each clock. Finally, I was responsible for preparing the manuscript.
