Atomic clock frequency ratios with fractional uncertainty $\leq 3.2 \times 1 0^{- 18}$

Alexander Aeppli, Willa J. Arthur-Dworschack, Kyle Beloy +24

We report high-precision frequency ratio measurements between optical atomic clocks based on $^{27}$ Al $^{+}$ , $^{171}$ Yb, and $^{87}$ Sr. With total fractional uncertainties at or bel…

Blackbody radiation Zeeman shift in Rydberg atoms

K. Beloy, B. D. Hunt, R. C. Brown +5

We consider the Zeeman shift in Rydberg atoms induced by room-temperature blackbody radiation (BBR). BBR shifts to the Rydberg levels are dominated by the familiar BBR Stark shift.…

Cryogenic Optical Lattice Clock with $1.7 \times 1 0^{- 20}$ 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…
