Scientists have measured the influence of the ambient temperature on strontium atoms for the first time – measurement uncertainty has been reduced by one order of magnitude. An optical clock with ...

Researchers at the Ye Lab at JILA (the National Institute of Standards and Technology and the University of Colorado Boulder) and University of Delaware recently created a highly precise optical ...

Heralding a new age of terrific timekeeping, physicists have unveiled an experimental strontium atomic clock that has set new world records for both precision and stability -- key metrics for the ...

The newest strontium clock is the most precise yet because scientists take the temperature of the environment, accounting for its effects. The two thermometers are shown in the center of the ...

An optical clock based on neutral strontium atoms is considered to be a leading candidates for definition a "new" second. The clock’s frequency can now be determined more accurately - by up to an ...

BOULDER, Colo.- A next-generation atomic clock that tops previous records for accuracy in clocks based on neutral atoms has been demonstrated by physicists at JILA, a joint institute of the Commerce ...

Call it a clock’s clock. Researchers say they have developed the world’s most precise and accurate clock – besting the World’s current timekeeping record holder — the National Institute of Standards ...

PORTLAND, Ore. — A candidate to be the next-generation atomic clock is based on the heavy metal strontium and uses a laser lattice to suspend super-cooled atoms. The result was a 430-THz time ...

Not satisfied with the accuracy of the "quantum logic clock" (which only gains or loses one second every 3.7 billion years), the National Institute of Standards and Technology (NIST) and JILA have ...

BOULDER, Colo -- Heralding a new age of terrific timekeeping, a research group led by a National Institute of Standards and Technology (NIST) physicist has unveiled an experimental strontium atomic ...
