Abstract: This paper presents the development of a MEMS-based reflection-type vapor cell combined with metasurfaces, which function as essential optical components for a microfabricated atomic clock.

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

The emission of photons by excited nuclei has been explored for timekeeping and sensing, but nuclear processes that eject electrons offer practical advantages. Electrons in atoms can exist only in ...

Denny Chimes is now synced to atomic clock precision, making the clock tower more accurate than ever. Thejesh Bandi, an associate professor in the department of physics and principal investigator of ...
