For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ...

Nuclear effect The deformed shape of the ytterbium-173 nucleus (right) makes it possible to excite the clock transition with a relatively low-power laser. The same transition is forbidden (left) if ...

A string of experiments using thorium-229 nuclei has brought the long-theorized nuclear clock closer to reality, producing frequency measurements stable enough to challenge the atomic clocks that ...

Add Yahoo as a preferred source to see more of our stories on Google. With three months remaining in Haiti’s rocky political transition, United Nations Security Council members are calling on the ...

Claire Cramer, the executive director of quantum science at the University of California, Berkeley, who was in attendance, expressed optimism about the potential of solid-state nuclear clocks: “This ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

Optical clocks are highly precise timekeeping devices that measure time by tracking the oscillations of light, as opposed to microwaves, like conventional atomic clocks. The accuracy of these clocks ...

With three months remaining in Haiti’s rocky political transition, United Nations Security Council members are calling on the country’s leaders and politicians to quickly set aside their differences ...
