Real-time geopotentiometry with synchronously linked optical lattice clocks
Tetsushi Takano, Masao Takamoto, Ichiro Ushijima +7
According to the Einstein's theory of relativity, the passage of time changes in a gravitational field. On earth, raising a clock by one centimetre increases its tick rate by 1.1 p…

Cryogenic optical lattice clocks with a relative frequency difference of
Ichiro Ushijima, Masao Takamoto, Manoj Das +2
Time and frequency are the most accurately measurable quantities, providing foundations for science and modern technologies. The accuracy relies on the SI (Systéme International) s…
