Atomic clock frequency ratios with fractional uncertainty $\leq 3.2 \times 1 0^{- 18}$

Alexander Aeppli, Willa J. Arthur-Dworschack, Kyle Beloy +24

We report high-precision frequency ratio measurements between optical atomic clocks based on $^{27}$ Al $^{+}$ , $^{171}$ Yb, and $^{87}$ 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 $5.5 \times 1 0^{- 19}$ 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 $5.5 \times 1 0^{- 19}$ and fractional frequency stability of $3.5 \times10^{-16}/\sqrt{τ/\mathrm{s…
