Two-photon Doppler-free spectroscopy of the Rydberg transition for quantum sensing in ytterbium

Benjamin D. Hunt, Kyle Beloy, Roger C. Brown +5

Here we report atomic structure calculations and experimental observations of the two-photon transition in Yb. The unique level structure of…

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…

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…

Clock-line-mediated Sisyphus Cooling

Chun-Chia Chen, Jacob L. Siegel, Benjamin D. Hunt +6

We demonstrate sub-recoil Sisyphus cooling using the long-lived clock state in alkaline-earth-like ytterbium. A 1388 nm optical standing wave nearly resonant w…

Ratchet Loading and Multi-Ensemble Operation in an Optical Lattice Clock

Youssef S. Hassan, Takumi Kobayashi, Tobias Bothwell +6

We demonstrate programmable control over the spatial distribution of ultra-cold atoms confined in an optical lattice. The control is facilitated through a combination of spatial ma…
