$^{88}$ Sr $^{+}$ optical clock with $7.9 \times 1 0^{- 19}$ systematic uncertainty and measurement of its absolute frequency with $9.8 \times 1 0^{- 17}$ uncertainty

T. Lindvall, T. Fordell, K. J. Hanhijärvi +4

We report on a $^{88}$ Sr $^{+}$ single-ion optical clock with an estimated fractional systematic uncertainty of $7.9 \times 1 0^{- 19}$ . The low uncertainty is enabled by small rf loss…

Noise-induced servo errors in optical clocks utilizing Rabi interrogation

T. Lindvall, A. E. Wallin, K. J. Hanhijärvi +1

We show that in optical clocks based on Rabi interrogation, both laser-frequency and magnetic-field flicker ( $1/ f$ ) noise with zero mean can lead to servo errors at the $1 0^{- 18}$ …
