NASA scientists are moving on from typical atomic clocks and using optical light and strontium atoms to build a new future.

A research team led by Prof. Chang Hong from the National Time Service Center (NTSC) of the Chinese Academy of Sciences (CAS) ...

Every clock in your house probably tells a slightly different time. Now picture those clocks as the most precise instruments humanity has ever built, so accurate that they wouldn't lose or gain a ...

In a new study, researchers carried out the most extensive coordinated comparison of optical clocks to date by operating ...

This holiday, we bring you a meditation on time ... and clocks. There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend on them for GPS location ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use ...

Atomic clocks and frequency standards represent the pinnacle of precision timekeeping technology. By harnessing the natural oscillatory behaviour of atoms, these devices deliver unparalleled ...

So steady are these oscillations that atomic clocks keep better time than the spinning earth itself The "pendulums" which regulate them are the vibrating parts of atoms or molecules.

02:01 Atomic scientists set ‘Doomsday Clock’ closer to midnight than ever ... the peer-reviewed journal Nature on March 8. They used strontium titanate (SrTiO3), a quantum material with ...

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 ...

The new models also address industry demand for alternatives to legacy magnetic cesium clocks that are more difficult to manage over time.
