Classical-limit formula for matrix elements between bound states of distinct one-dimensional potentials
K. Beloy
A classical-limit formula is derived for matrix elements between bound states of distinct one-dimensional potentials. We leave open the physical interpretation of the potentials, b…
Atomic clock frequency ratios with fractional uncertainty
Alexander Aeppli, Willa J. Arthur-Dworschack, Kyle Beloy +24
We report high-precision frequency ratio measurements between optical atomic clocks based on Al, Yb, and 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 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…
Direct measurement of the 3P0 clock state natural lifetime in 87Sr
Jonathan Dolde, Dhruva Ganapathy, Xin Zheng +3
Optical lattice clocks based on the narrow (5s2)1S0 - (5s5p)3P0 transition in neutral strontium (Sr) are among the most precise and accurate measurement devices in existence. Altho…
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…
