Researchers at Wuhan University (WHU) in China have produced a commercially manufacturable atomic clock less than one-seventh the size of its smallest US counterpart for use in satellites, drones and ...

For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ...

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 ...

Physicists are getting closer to creating a long-sought ‘nuclear clock’. This device would keep time by measuring energy ...

For all our telescopes and colliders, dark matter has remained an elusive ghost for the better part of a century. It outweighs everything we see by a factor of five, yet it slips past every detector ...

Scientists have taken another giant step towards building the most precise clock ever imagined—one that could display not only the passage of time, but shifting rules of nature itself. An ...

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...
