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…

Hyperfine-mediated electric quadrupole shifts in Al $^{+}$ and In $^{+}$ ion clocks

K. Beloy, D. R. Leibrandt, W. M. Itano

We evaluate the electric quadrupole moments of the $^{1} S_{0}$ and $^{3} P_{0}$ clock states of $^{27}$ Al $^{+}$ and $^{115}$ In $^{+}$ . To capture all dominant contributions, our analysis…

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…
