Kyle Beloy (Fed)

Kyle Beloy is a research scientist in the Time and Frequency Division at NIST. The most accurate and precise measurements in science are underpinned by atomic clocks. Kyle's research focuses on advancing the state-of-the-art for atomic clocks, including the ytterbium optical lattice clocks at NIST. This includes developing strategies to address various effects that afflict the clocks at new levels of metrological performance.

Lattice Light Shift Evaluations In a Dual-Ensemble Yb Optical Lattice Clock

Author(s)
Tobias Bothwell, Roger Brown, Benjamin Hunt, Jacob Siegel, Tanner Grogan, Youssef Hassan, Kyle Beloy, Andrew Ludlow, Kurt Gibble, Takumi Kobayashi, Marianna Safronova, Sergey Porsev
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

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

Author(s)
Youssef Hassan, Takumi Kobayashi, Tobias Bothwell, Jacob Siegel, Benjamin Hunt, Kyle Beloy, Kurt Gibble, Tanner Grogan, Andrew Ludlow
We demonstrate programmable control over the spatial distribution of ultra-cold atoms confined in an optical lattice. The control is facilitated through a

Clock-line-mediated Sisyphus Cooling

Author(s)
Jacob Siegel, Benjamin Hunt, Tanner Grogan, Youssef Hassan, Kyle Beloy, Roger Brown, Andrew Ludlow, Chun-Chia Chen, Kurt Gibble
We demonstrate sub-recoil Sisyphus cooling using the long-lived 3P0 clock state in alkaline-earthlike ytterbium. A 1388 -nm optical standing wave nearly
