Power shut off across Colorado last week as hurricane-force winds swept across the state. In Boulder, one of those outages caused time to briefly stand still.

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, researchers ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

NIST traced the problem to its Boulder, Colorado campus, where a prolonged utility power outage disrupted operations. The ...

Atomic clocks have long served as the benchmark for precise timekeeping by utilising the stable frequency of atomic transitions as a reference. Recent developments focus on harnessing coherent ...

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with ...

A powerful storm in Boulder, Colorado, caused a power outage that knocked the U.S. official atomic clock out of sync, ...

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

NIST restored the precision of its atomic clocks after a power outage caused by a power outage disrupted operations. Discover ...

This particular clock is technically an ion clock, which is different from the more common atomic clocks that are based on measuring the resonant frequencies of a single cesium atom to regulate time ...

A revolutionary achievement could pave the way for smaller, more efficient nuclear clocks. Last year, a research team led by UCLA achieved a milestone scientists had pursued for half a century. They s ...
