Absolute frequency measurement of the $^{2}$ S $_{1/2} \to^{2}$ F $_{7/2}$ optical clock transition in $^{171}$ Yb $^{+}$ with an uncertainty of $4 \times 1 0^{- 16}$ using a frequency link to International Atomic Time

Charles F. A. Baynham, Rachel M. Godun, Jonathan M. Jones +8

The highly forbidden $^{2}$ S $_{1/2} \to^{2}$ F $_{7/2}$ electric octupole transition in $^{171}$ Yb $^{+}$ is a potential candidate for a redefinition of the SI second. We present a…

Rydberg Electrometry for Optical Lattice Clocks

William Bowden, Richard Hobson, Paul Huillery +3

Electrometry is performed using Rydberg states to evaluate the quadratic Stark shift of the $5 s^{2}$ $^{1} S_{0} - 5 s 5 p$ $^{3} P_{0}$ clock transition in strontium. By measurin…
