Nuclear clocks should be more robust and portable than the best available clocks today because nuclei are hard to perturb and ...

World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wall clock ...

Two teams of physicists have made the world’s first nuclear clocks. These radical new devices use fluctuations in the energy states of an atom’s nucleus to keep time, rather than those of its ...

New thorium-229-based time standard reaches 1-second drift in 3 million years and promises compact, robust optical clocks ...

What looks like an aerial shot of an alien landscape is actually a scanning electron microscope view of a test glass surface, acquired as part of a project to improve the lifetime of spaceborne atomic ...

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 paired ...

How does a clock become precise enough to guide a spacecraft across interstellar distance without drifting a single second ...

Can dark matter interact with photons and influence atomic structure? A case for optical atomic clocks: Two different types of such clocks were compared at the Physikalisch-Technische Bundesanstalt ...

Without precise time, the modern world collapses - from GPS to the electricity grid. And Switzerland is one of the clock ...
