Optical atomic clocks are 100 times more precise than cesium clocks. Scientists are using them to search for dark matter and measure gravity.

This has now paved the way for a multi-ion optical ytterbium clock that combines the high accuracy of single-ion clocks with ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...

Our self-contained Google Colab notebooks is the easiest way to play with Diffusion Policy. We provide separate notebooks for state-based environment and vision-based environment. . ├── config.yaml ...

Abstract: With the aim of developing a cold cesium atom primary frequency standard, a cesium-133 magneto-optical trap (MOT) has been developed at CENAM's Time and Frequency Division. In this paper we ...

“Atomic clocks and our computer networks are the new, far superior form of time measurement, but we’re forcing them to keep in sync with this older form of measurement,” remarks Dr. David Gozzard, an ...

A group of Brazilian researchers has presented an innovative proposal to resolve a decades-old debate among theoretical physicists: how many fundamental constants are needed to describe the observable ...

We need it to run our lives and often become slaves to it but are still not sure about what it is. That “it” is time. What is this thing that we all know about but may not really understand? I admit ...

Cesium has a long half life and persists in the environment.In their analyses of the beaches,the scientists detected not only cesium 137,which may have come from the Dai ichi plant or from nuclear ...
