Accurate recovery of the two linewidths hidden in laser beatnote statistics
Jingming Chen, Yuanchen Qi, Yuzheng Pang +12
Photons from ultrastable lasers can remain coherent over distances approaching the Earth-Sun separation, enabling optical clocks projected to lose less than one second over the age…

Measurement of Differential Static Polarizability and Frequency of an Inner-Shell Orbital Clock Transition in Lattice-Trapped 174Yb
Yao Yuan, Wang Congyu, Zou Jinpeng +4
Additional clock transitions of ytterbium atoms based on inner-shell orbital transition could benefit the search for new physics beyond the Standard Model. Observation of these tra…
