Atomic clock performance beyond the geodetic limit
W. F. McGrew, X. Zhang, R. J. Fasano +9
The passage of time is tracked by counting oscillations of a frequency reference, such as Earth's revolutions or swings of a pendulum. By referencing atomic transitions, frequency…

Faraday-shielded, DC Stark-free optical lattice clock
K. Beloy, X. Zhang, W. F. McGrew +7
We demonstrate the absence of a DC Stark shift in an ytterbium optical lattice clock. Stray electric fields are suppressed through the introduction of an in-vacuum Faraday shield.…
