Inverse identification of thermal-radiative parameters for reduced effective-temperature uncertainty in an ion optical clock
Jie Zhao, Yani Zuo, Shaoyang Dai +8
The blackbody-radiation (BBR) shift remains a leading systematic uncertainty of room-temperature single-ion optical clocks. Accurate evaluation of this shift requires the effective…

Realization of the SI Second Defined by Geometric Mean of Multiple Clock Transitions
Fang Fang, Chaowei Wang, Yani Zuo +1
The current definition of the SI second is based on the 133Cs ground-state hyperfine transition in the microwave domain, with the most accurate realizations achieving fractional fr…
