Atomic clocks, combined with precise astronomical measurements, have revealed that the length of a day is suddenly getting longer, and scientists don't know why.
Time is flying. Literally.
Atoms are notoriously difficult to control. They zigzag like fireflies, tunnel out of the strongest containers and jitter even at temperatures near absolute zero.
Quantum clocks are shrinking, thanks to new technologies developed at the University of Birmingham-led UK Quantum Technology Hub Sensors and Timing
The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of atomic clocks as well as ...
A team of researchers at the National University of Singapore has developed a customized magneto-optical trap (MOT) to cool indium atoms to near absolute zero. In their paper published in the journal Physical Review A, the ...
Erbium-doped fiber amplifiers (EDFAs) are devices that can provide gain to the optical signal power in optical fibers. They are often used in long-distance communication fiber optic cables and fiber-based lasers. Invented ...
Quark-gluon plasma (QGP) is a state of matter existing at extremely temperatures and densities, such as those that occur in collisions of hadrons (protons, neutrons and mesons). Under so-called "normal" conditions, quarks ...
Powerful enough to spot a golf ball on the moon, the Event Horizon Telescope (EHT) is a network of radio dishes designed to detect the light cast when matter disappears into the maw of a black hole.
At simultaneous press conferences around the world, including at a National Science Foundation-sponsored press conference at the U.S. National Press Club in Washington, D.C., astronomers have unveiled the first image of the ...
