New nuclear clock precision could help redefine the second, researchers say

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 ...

Scientists Think Time Could Move Fast and Slow All at Once. They’re About to Prove It.

In Albert Einstein’s Special Theory of Relativity, the concept of “time dilation” illustrates that the flow of time is ...

Using atomic nuclei could allow scientists to read time more precisely than ever – what this research could mean for future clocks

Atomic clocks exploit the properties of atoms to create incredibly precise 'ticks.' Nate Phillips, NIST Most clocks, from ...

Physicists revive 1990s laser concept to propose a next-generation atomic clock

Researchers in the US and Germany have unveiled a theoretical blueprint for an atomic clock driven by a highly synchronized ...

Ion-clock transition could benefit quantum computing and nuclear physics

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 ...
