In 2008, a team of UCLA-led scientists proposed a scheme to use a laser to excite the nucleus of thorium atoms to realize extremely accurate, portable clocks. Last year, they realized this ...
For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...
What if the key to unlocking new physics lies in keeping better time? Inside the quiet journey to build a nuclear clock so precise, it could redefine our understanding of reality. Researchers are ...
