Improved absolute frequency measurement of $^{171}$ Yb at NMIJ with uncertainty below $2 \times 1 0^{- 16}$

Takumi Kobayashi, Akiko Nishiyama, Kazumoto Hosaka +6

We report improved absolute frequency measurement of the $^{1}$ S $_{0} -^{3}$ P $_{0}$ transition of $^{171}$ Yb at National Metrology Institute of Japan (NMIJ) by comparing the $^{171}…

Generation of a precise time scale assisted by a near-continuously operating optical lattice clock

Takumi Kobayashi, Daisuke Akamatsu, Kazumoto Hosaka +8

We report on a reduced time variation of a time scale with respect to Coordinated Universal Time (UTC) by steering a hydrogen-maser-based time scale with a near-continuously operat…
