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…
Two-photon optical frequency reference with active ac Stark shift cancellation
V. Gerginov, K. Beloy
An optical reference based on a two-photon optical transition with ac Stark shift cancellation is proposed. The reference uses two interrogating laser fields at different frequenci…
First observation with global network of optical atomic clocks aimed for a dark matter detection
P. Wcisło, P. Ablewski, K. Beloy +19
We report on the first earth-scale quantum sensor network based on optical atomic clocks aimed at dark matter (DM) detection. Exploiting differences in the susceptibilities to the…
Hyper-Ramsey spectroscopy with probe laser intensity fluctuations
K. Beloy
We examine the influence of probe laser intensity fluctuations on hyper-Ramsey spectroscopy. We assume, as is appropriate for relevant cases of interest, that the probe laser inten…
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.…
