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…
Hyperpolarizability and operational magic wavelength in an optical lattice clock
R. C. Brown, N. B. Phillips, K. Beloy +11
Optical clocks benefit from tight atomic confinement enabling extended interrogation times as well as Doppler- and recoil-free operation. However, these benefits come at the cost o…
Absolute frequency measurement of the 1S0 - 3P0 transition of 171Yb
Marco Pizzocaro, Pierre Thoumany, Benjamin Rauf +6
We report the absolute frequency measurement of the unperturbed transition 1S0 - 3P0 at 578 nm in 171Yb realized in an optical lattice frequency standard. The absolute frequency is…
Ultra-stable optical clock with two cold-atom ensembles
M. Schioppo, R. C. Brown, W. F. McGrew +10
Atomic clocks based on optical transitions are the most stable, and therefore precise, timekeepers available. These clocks operate by alternating intervals of atomic interrogation…
