Cryogenic Optical Lattice Clock with Blackbody Radiation Stark Uncertainty
Youssef S. Hassan, Kyle Beloy, Jacob L. Siegel +9
Controlling the Stark perturbation from ambient thermal radiation is key to advancing the performance of many atomic frequency standards, including state-of-the-art optical lattice…
Coordinated international comparisons between optical clocks connected via fiber and satellite links
Thomas Lindvall, Marco Pizzocaro, Rachel M. Godun +62
Optical clocks provide ultra-precise frequency references that are vital for international metrology as well as for tests of fundamental physics. To investigate the level of agreem…
Improved absolute frequency measurement of Yb at NMIJ with uncertainty below
Takumi Kobayashi, Akiko Nishiyama, Kazumoto Hosaka +6
We report improved absolute frequency measurement of the SP transition of Yb at National Metrology Institute of Japan (NMIJ) by comparing the $^{171}…
Measurement of transition frequencies and hyperfine constants of molecular iodine at 520.2 nm
Akiko Nishiyama, Sho Okubo, Takumi Kobayashi +2
We measured the transition frequencies of the hyperfine components in the four lines (P(34) 39-0, R(36) 39-0, P(33) 39-0, and R(35) 39-0) of the B-X transitions of molecular iodine…
Lattice Light Shift Evaluations In a Dual-Ensemble Yb Optical Lattice Clock
Tobias Bothwell, Benjamin D. Hunt, Jacob L. Siegel +9
In state-of-the-art optical lattice clocks, beyond-electric-dipole polarizability terms lead to a break-down of magic wavelength trapping. In this Letter, we report a novel approac…
