Frequency ratios of Sr, Yb and Hg based optical lattice clocks and their applications

Masao Takamoto, Ichiro Ushijima, Manoj Das +8

This article describes the recent progress of optical lattice clocks with neutral strontium ( $^{87}$ Sr), ytterbium ( $^{171}$ Yb) and mercury ( $^{199}$ Hg) atoms. In particular, we pr…

Frequency Ratio of $^{199}$ Hg and $^{87}$ Sr Optical Lattice Clocks beyond the SI Limit

Kazuhiro Yamanaka, Noriaki Ohmae, Ichiro Ushijima +2

We report on a frequency ratio measurement of a $^{199}$ Hg-based optical lattice clock referencing a $^{87}$ Sr-based clock. Evaluations of lattice light shift, including atomic…
