Absolute frequency of $^{87} Sr$ at $1.8 \times 1 0^{- 16}$ uncertainty by reference to remote Primary Frequency Standards

Nils Nemitz, Tadahiro Gotoh, Fumimaru Nakagawa +4

The optical lattice clock NICT-Sr1 regularly reports calibration measurements of the international timescale TAI. By comparing measurement results to the reports of eight Primary F…

Frequency ratio of an $^{115}$ In $^{+}$ ion clock and a $^{87}$ Sr optical lattice clock

Nozomi Ohtsubo, Ying Li, Nils Nemitz +4

We report on the first frequency ratio measurement of an $^{115}$ In+ single ion clock and a $^{87}$ Sr optical lattice clock. A hydrogen maser serves as a reference oscillator to me…
