Observation and cancellation of the dc Stark shift in strontium optical lattice clocks
Jérôme Lodewyck, Michal Zawada, Luca Lorini +2
We report on the observation of a dc Stark frequency shift at the level by comparing two strontium optical lattice clocks. This frequency shift arises from the presence…
