A zero-dead-time strontium lattice clock with a stability at level
Xiao-Yong Liu, Peng Liu, Jie Li +20
Optical atomic clocks play a crucial role in fundamental physics, relativistic geodesy, and the future redefinition of the SI second. Standard operation relies on cyclic interrogat…

Improved systematic evaluation of a strontium optical clock with uncertainty below
Zhi-Peng Jia, Jie Li, De-Quan Kong +17
We report a systematic uncertainty of for the USTC Sr1 optical lattice clock, achieving accuracy at the level required for the roadmap of the redefinition of t…
