Improved Frequency Ratio Measurement with 87Sr and 171Yb Optical Lattice Clocks at NMIJ

Yusuke Hisai, Daisuke Akamatsu, Takumi Kobayashi +4

We report improved frequency ratio measurement with $^{87}$ Sr and $^{171}$ Yb optical lattice clocks at the National Metrology Institute of Japan (NMIJ). The $^{87}$ Sr optical latti…
