For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with ...

A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. NIST-F4 measures an ...

Researchers develop a method to count thorium-229 nuclear ticks, paving the way for high-precision nuclear clocks and sensors ...

A revolutionary achievement could pave the way for smaller, more efficient nuclear clocks. Last year, a research team led by UCLA achieved a milestone scientists had pursued for half a century. They s ...

Nuclear clocks are a technology researchers have been working toward for decades. New research in theoretical physics brings them closer to reality.

A research team from the University of California Los Angeles (UCLA), Ludwig Maximilian University of Munich (LMU), and Johannes Gutenberg University Mainz (JGU) has succeeded in exciting the atomic ...

The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...

(TNS) — In 2003, engineers from Germany and Switzerland began building a bridge across the Rhine River simultaneously from both sides. Months into construction, they found that the two sides did not ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency standard — ...
