Be optical lattice clocks with the fractional Stark shift up to the level of 10−19
New Journal of Physics, 2023 The energy levels and electric dipole ( $E1$ ) matrix elements of the ground state and low-lying excited states of Be atoms are calculated using the relativistic configuration interaction plus core polarization (RCICP) method. The static and dynamic $E1$

Deep Laser Cooling of Thulium Atoms to Sub-µK Temperatures in Magneto-Optical Trap
Atoms, 2023 Deep laser cooling of atoms, ions, and molecules facilitates the study of fundamental physics as well as applied research. In this work, we report on the narrow-line laser cooling of thulium atoms at the wavelength of 506.2nm with the natural linewidth ...

Frequency Standards and Metrology, 2009 At the previous Symposium on Frequency Standards and Metrology, H. Katori proposed using IS0 ---->3pO transitions in alkaline earth like atoms to make high performance optical clocks based on large numbers of neutral atoms tightly confined in an optical lattice.

Entanglement and spin-squeezing in a network of distant optical lattice clocks
, 2015 We propose an approach for collective enhancement of precision for remotely located optical lattice clocks and a way of generation of the Einstein-Podolsky-Rosen state of remote clocks.

Trapping of Neutral Mercury Atoms and Prospects for Optical Lattice Clocks [PDF]
, 2007 We report a vapor-cell magneto-optical trapping of Hg isotopes on the ${}^1S_0-{}^3P_1$ intercombination transition. Six abundant isotopes, including four bosons and two fermions, were trapped.

INO: Interplanetary network of optical lattice clocks [PDF]
International Journal of Modern Physics D, 2019 The new technique of measuring frequency by optical lattice clocks now approaches to the relative precision of [Formula: see text]. We propose to place such precise clocks in space and to use Doppler tracking method for detecting low-frequency gravitational wave below 1[Formula: see text]Hz. Our idea is to locate three spacecrafts at one A.U. distance (
