Blackbody radiation Zeeman shift in Rydberg atoms

Author(s)
Kyle Beloy, Benjamin Hunt, Roger Brown, Tobias Bothwell, Youssef Hassan, Jacob Siegel, Tanner Grogan, Andrew Ludlow
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

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
