Modeling motional energy spectra and lattice light shifts in optical lattice clocks
K. Beloy, W. F. McGrew, X. Zhang +5
We develop a model to describe the motional (i.e., external degree of freedom) energy spectra of atoms trapped in a one-dimensional optical lattice, taking into account both axial…
Towards Adoption of an Optical Second: Verifying Optical Clocks at the SI Limit
W. F. McGrew, X. Zhang, H. Leopardi +13
The pursuit of ever more precise measures of time and frequency is likely to lead to the eventual redefinition of the second in terms of an optical atomic transition. To ensure con…
Faraday-shielded, DC Stark-free optical lattice clock
K. Beloy, X. Zhang, W. F. McGrew +7
We demonstrate the absence of a DC Stark shift in an ytterbium optical lattice clock. Stray electric fields are suppressed through the introduction of an in-vacuum Faraday shield.…
Magic wavelengths for the transition in rubidium
E. A. Goldschmidt, D. G. Norris, S. B. Koller +5
Magic wavelengths, for which there is no differential ac Stark shift for the ground and excited state of the atom, allow trapping of excited Rydberg atoms without broadening the op…
