Highly charged Nd Ion: A potential candidate of $\upmu$Hz linewidth optical clocks for probing fundamental physics
Yan-mei Yu, Duo Pan, Shaolong Chen +3
An active optical clock based on highly charged Nd ion is proposed for the first time. The clock can offer ultra-narrow linewidth at the $\upmu$Hz-level which is more than t…

A liquid nitrogen-cooled Ca^+ optical clock with systematic uncertainty of 3*10^-18
Yao Huang, Baolin Zhang, Mengyan Zeng +6
Here we present a liquid nitrogen-cooled Ca^+ optical clock with an overall systematic uncertainty of 3*10^-18. In contrast with the room-temperature Ca^+ optical clock that we hav…

Probing Multiple Electric Dipole Forbidden Optical Transitions in Highly Charged Nickel Ions
Shi-Yong Liang, Ting-Xian Zhang, Hua Guan +13
Highly charged ions (HCIs) are promising candidates for the next generation of atomic clocks, owing to their tightly bound electron cloud, which significantly suppresses the common…
