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…
Excited-Band Coherent Delocalization for Improved Optical Lattice Clock Performance
Jacob Siegel, William McGrew, Youssef Hassan +5
We implement coherent delocalization as a tool for improving the two primary metrics of atomic clock performance: systematic uncertainty and instability. By decreasing atomic densi…
