New chip-based frequency combs demonstrate potential for portable atomic clocks
TL;DRScientists made smaller frequency combs that could enable portable atomic clocks.
Why it matters: Compact atomic clocks would improve GPS, telecommunications, and scientific instruments globally.
The world would look radically different without rulers and measuring tapes that fit into a pocket. Carpenters, fashion designers and engineers rely on these trusty tools to check the size of everything from a wooden board to a fabric swatch. But physicists who work with light…
