First-ever thorium-based nuclear atomic clock is a new tool to probe fundamental forces – and even hunt for dark matter
What you'll discover in this article ・The first thorium-229 nuclear clock has been achieved. ・It is not as precise as regular atomic clocks, but it could be a revolutionary tool in probing fundamental ...
Physicists have built the first stand-alone optical nuclear clock by locking a continuous-wave laser to the thorium-229 ...
Researchers in Austria have built the world’s first self-stabilizing nuclear clock, using thorium nuclei to keep its laser ...
China's nuclear clock is about six times more stable than Vienna's, as researchers push thorium-229 toward practical ...
(Patcharin Saenlakon/iStockphoto/Getty Images) The time-keeping offered by your watch or phone may be good enough for day-to-day life, but scientists are much more ambitious in terms of precision, and ...
Atomic clocks are a class of clocks that leverage resonance frequencies of atoms to keep time with high precision. While these clocks have become increasingly advanced and accurate over the years, ...
As the world considers redefining the precise length of a second, Singapore’s Centre for Quantum Technologies has delivered a new contender for the ultimate master timekeeper. Tests of their new ...
A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known as NIST-F4, ...
The heart of a minuscule atomic clock—believed to be 100 times smaller than any other atomic clock—has been demonstrated by scientists at the Commerce Department’s National Institute of Standards and ...
