An experimental atomic clock based on ytterbium atoms is about four times ... says NIST physicist Chris Oates, an author of the new paper. The NIST ytterbium clock is based on about 30,000 heavy metal atoms …
A pair of experimental atomic clocks based on ytterbium atoms has set a new record for stability, researchers said. The clocks act like 21st-century pendulums or metronomes that could swing back and forth with perfect …
The more stable the clock, the better its measurement power. The new ytterbium lattice 'double clock' is the most stable clock in the world, although another NIST atomic clock, based on strontium and located at JILA, …
Ytterbium is at the center of what could be the world’s most advanced atomic clock — a clock so stable ... or helping define a new, more precise standard for the second. But for Sherman, who grew up in Las Vegas, the …
A new ... clock in Germany has now dethroned JILA's optical lattice atomic clock as the world's most accurate timepiece ever built. With an unprecedented level of accuracy, the optical single-ion clock works by …
According to statistical measurements conducted on the new atomic clock ... The stability of the strontium clock is similar to that of the ytterbium atomic clock unveiled by NIST investigators back in August 2013. All …
NIST explains that the ticks of any atomic clock must be averaged over a period of time to provide the best results. One major benefit of the very high stability shown by the new ytterbium clocks is that precise results …
Heralding a new age of terrific timekeeping ... The strontium clock's stability—the extent to which each tick matches the duration of every other tick—is about the same as NIST's ytterbium atomic clock, another world …
Scientists at the National Institute of Standards and Technology have gotten a step closer to figuring out time with a new ytterbium-based atomic clock. The new clock is so accurate that the differences in measuring one …
Take our quiz Atomic clocks, which are used to calibrate ... Instead of microwaves, this new pair of clocks uses lasers to excite the atoms. And instead of cesium, it uses ytterbium, a rare metal named after the Swedish …
