Atomic clock frequency ratios with fractional uncertainty
Alexander Aeppli, Willa J. Arthur-Dworschack, Kyle Beloy +24
We report high-precision frequency ratio measurements between optical atomic clocks based on Al, Yb, and Sr. With total fractional uncertainties at or bel…
Doppler Shift Mitigation in a Chip-Scale Atomic Beam Clock
Alexander Staron, Gabriela Martinez, Nicholas Nardelli +3
Chip-scale microwave atomic systems based on thermal atomic beams offer a promising approach to realize low-power and low-drift clocks for timing holdover applications. Miniature b…
High-Stability Single-Ion Clock with Systematic Uncertainty
Mason C. Marshall, Daniel A. Rodriguez Castillo, Willa J. Arthur-Dworschack +10
We report a single-ion optical atomic clock with fractional frequency uncertainty of and fractional frequency stability of $3.5 \times10^{-16}/\sqrt{τ/\mathrm{s…
Optical coherence between atomic species at the second scale: improved clock comparisons via differential spectroscopy
May E. Kim, William F. McGrew, Nicholas V. Nardelli +9
Comparisons of high-accuracy optical atomic clocks \cite{Ludlow2015} are essential for precision tests of fundamental physics \cite{Safronova2018}, relativistic geodesy \cite{McGre…
