Optically guided atom interferometer tuned to magic wavelength
Tomoya Akatsuka, Tadahiro Takahashi, Hidetoshi Katori
We demonstrate an atom interferometer operating on the clock transition of Sr atoms in a "magic" optical guide, where the light shift perturbations of the gu…

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…

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 (Sr), ytterbium (Yb) and mercury (Hg) atoms. In particular, we pr…
