Abstract

Optical lattice clocks (OLCs) are now the most stable and accurate timekeepers in the world, with fractional uncertainties equivalent to neither losing nor gaining a second over the entire age of the universe. This unprecedented level of metrological precision offers sensitivity to new physical phenomena, opening the door to exciting and unusual applications. I will give a brief overview of emerging applications of OLCs, including gravitational wave detection, tests of general relativity, and searches for physics beyond the Standard Model. I will discuss the concept and basic operating principles of the multiplexed OLC we have constructed. Finally, I will present recent experimental progress we have made towards measuring the gravitational redshift at the centimeter scale using the multiplexed OLC.
