Radium Ion Optical Clock
C. A. Holliman, M. Fan, A. Contractor +2
We report the first operation of a Ra optical clock, a promising high-performance clock candidate. The clock uses a single trapped Ra ion and operates on the $7…
Frequency Ratio Measurements with 18-digit Accuracy Using a Network of Optical Clocks
Boulder Atomic Clock Optical Network, Collaboration, : +35
Atomic clocks occupy a unique position in measurement science, exhibiting higher accuracy than any other measurement standard and underpinning six out of seven base units in the SI…
Measurements of Al and Mg magnetic constants for improved ion clock accuracy
S. M. Brewer, J. -S. Chen, K. Beloy +14
We have measured the quadratic Zeeman coefficient for the optical clock transition in Al, ~MHz/T, an…
Systematic uncertainty due to background-gas collisions in trapped-ion optical clocks
A. M. Hankin, E. R. Clements, Y. Huang +5
We describe a framework for calculating the frequency shift and uncertainty of trapped-ion optical atomic clocks caused by background-gas collisions, and apply this framework to an…
