The US Air Force is turning to atomic clock technology to help coordinate swarms of small drones in environments where traditional satellite navigation is jammed or spoofed, according to a new request ...

Why are there atomic clocks but no nuclear clocks? After all, an atom's nucleus is typically surrounded by many electrons, so in principle it should be less susceptible to outside noise (in the form ...

Every single day, humans rely on hundreds of hidden clocks. GPS location, Internet stability, stock trading, power grid management ... all rely on atomic clocks in order to work. Many of those clocks ...

Physicists have demonstrated all the ingredients of a nuclear clock — a device that keeps time by measuring tiny energy shifts inside an atomic nucleus. Such clocks could lead to vast improvements in ...

Researchers demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...

For many years, scientists all around the world have been working towards this goal, now suddenly things are happening very fast: it was only in April that a team led by Prof Thorsten Schumm (TU Wien, ...

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 ...
