All papers · ⁸⁸Sr⁺ optical clock with 7.9×10⁻¹⁹ systematic uncertainty and measurement of its absolute frequency with 9.8×10⁻¹⁷ uncertainty
Clock self-comparison Allan deviation (ADEV) against averaging time $\tau$ (s), log-log: probe times 137 ms (circles), 137 ms EQS-free (crosses) and 202 ms (diamonds), with the slopes $2.7\times10^{-15}\,\tau^{-1/2}$ (dashed) and $2.0\times10^{-15}\,\tau^{-1/2}$ (dash-dot).
