Don't let the titanium metal walls or the sapphire windows fool you. It's what's on the inside of this small, curious device that could someday kick off a new era of navigation.
Integrated photonics allow us to build compact, portable, low-power chip-scale optical systems used in commercial products, revolutionizing today's optical datacenters and communications. But integrating on-chip optical gain ...
A team of researchers at the JILA, National Institute of Standards and Technology at the University of Colorado has found a way to use an atomic clock to demonstrate a principle of general relativity. The team has published ...
An international research team, with the participation of the Institute of Molecular Science (ICMol) of the University of Valencia, has achieved spin-electric control in molecular nanomagnets. This fact offers great advantages ...
Particles called neutrons are typically very content inside atoms. They stick around for billions of years and longer inside some of the atoms that make up matter in our universe. But when neutrons are free and floating alone ...
For more than two years, NASA's Deep Space Atomic Clock has been pushing the timekeeping frontiers in space. On Sept. 18, 2021, its mission came to a successful end.
Based on the strontium optical lattice clock platform, a research team led by Prof. Chang Hong from the National Time Service Center of the Chinese Academy of Sciences, together with Zhang Xuefeng from Chongqing University ...
On the cover of the Pink Floyd album Dark Side of the Moon, a prism splits a ray of light into all the colors of the rainbow. This multicolored medley, which owes its emergence to the fact that light travels as a wave, is ...
It would take 15 billion years for the clock that occupies Jun Ye's basement lab at the University of Colorado to lose a second—about how long the universe has existed.
