Direct measurement of the 3P0 clock state natural lifetime in 87Sr
Jonathan Dolde, Dhruva Ganapathy, Xin Zheng +3
Optical lattice clocks based on the narrow (5s2)1S0 - (5s5p)3P0 transition in neutral strontium (Sr) are among the most precise and accurate measurement devices in existence. Altho…

Impacts of random filling on spin squeezing via Rydberg dressing in optical clocks
Jacques Van Damme, Xin Zheng, Mark Saffman +2
We analyze spin squeezing via Rydberg dressing in optical lattice clocks with random fractional filling. We compare the achievable clock stability in different lattice geometries,…
