$^{88}$ 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. HanhijÃ¤rvi +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…

$^{115}$ In $^{+}$ - $^{172}$ Yb $^{+}$ Coulomb crystal clock with $2.5 \times 1 0^{- 18}$ systematic uncertainty

H. N. Hausser, J. Keller, T. Nordmann +17

We present a scalable mixed-species Coulomb crystal clock based on the $^{1} S_{0}$ $\leftrightarrow$ $^{3} P_{0}$ transition in $^{115}$ In $^{+}$ . $^{172}$ Yb $^{+}$ ions are co-trapped and used f…
