Optical atomic clock review
WebMar 5, 2024 · This issue would seem to present a dilemma: Adding atoms to the optical lattice provides a larger ensemble and therefore a higher precision measurement. But it also exacerbates the role of atom-atom interactions, which modify the clock-transition frequency in direct proportion to the atomic density [ 8, 9 ]. WebFeb 10, 2016 · The PTB scientists are the first to have reached the finishing line using a single-ion clock. Their optical ytterbium clock achieved a relative systematic measurement uncertainty of 3 10 -18....
