The precision of the nuclear clock is predicted to surpass that of atomic clocks in two to three years, and should also be ...

Why are there atomic clocks but no nuclear clocks? After all, an atom's nucleus is typically surrounded by many electrons, so ...

Chinese officials say that the weapon can be used to suppress the signals of American GPS and other satellites.

A new ultrafast laser platform generates ultra-broadband UV frequency combs that could enhance high-resolution atomic and ...

If the laser is tuned just right ... They're extremely precise. The newest optical atomic clocks at JILA, for example, can detect the change in gravity if you lift them up by just a fraction ...

Researchers have developed a new ultrafast laser platform that generates ultra-broadband ultraviolet (UV) frequency combs ...

Atomic clocks use the oscillations of atoms as timekeeping ... in energy states among a batch of neutral strontium atoms, laser-cooled and trapped into a lattice formed by laser beams.

Atomic clocks are the most accurate timekeeping devices we have. They work by locking an ultraprecise, frequency comb laser to a narrow linewidth transition in an atom. The higher the transition’s ...

With access to a 10-MHz timebase from a cesium fountain atomic clock — no less a clock than the one that’s used to define the SI second, by the way — [Daniel] looked for ways to sync the ...

Atomic clocks measure time by tuning laser light to frequencies that cause electrons to jump between energy levels. However, compared with the electrons in atomic clocks, the mechanisms within a ...
