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 ...

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 ...

Researchers are looking for new ways to improve timekeeping because even small gains in stability can help physicists discover subtle physical effects. The thorium-229 nuclear clock is a newer venture ...
