In a new study, U.S. and Austrian physicists have observed quantum entanglement among "billions of billions" of flowing electrons in a quantum critical material. The research, which appears this week in Science, examined the electronic and magnetic behavior of a "strange... Continue Reading →
On a hillside above Stanford University, the SLAC National Accelerator Laboratory operates a scientific instrument nearly 2 miles long. In this giant accelerator, a stream of electrons flows through a vacuum pipe, as bursts of microwave radiation nudge the particles... Continue Reading →
Born on 5 December 1868 in Königsberg, Prussia, theoretical physicist Arnold Sommerfeld was a pioneer of quantum and atomic physics. Sommerfeld started out studying mathematics, earning his PhD from the University of Königsberg in 1891, when he was just 23... Continue Reading →
For decades, scientists have speculated about the origin of the electromagnetic radiation emitted from celestial regions that host black holes and neutron stars -- the most mysterious objects in the universe. Astrophysicists believe that this high-energy radiation -- which makes... Continue Reading →
Using the first new method in half a century for measuring the size of the proton via electron scattering, the PRad collaboration has produced a new value for the proton's radius in an experiment conducted at the Department of Energy's... Continue Reading →
New measurements of the rate of expansion of the universe, led by astronomers at the University of California, Davis, add to a growing mystery: Estimates of a fundamental constant made with different methods keep giving different results. "There's a lot... Continue Reading →
The Nobel Prize in Physics 2019 was awarded "for contributions to our understanding of the evolution of the universe and Earth's place in the cosmos" with one half to James Peebles "for theoretical discoveries in physical cosmology", the other half... Continue Reading →
Giant molecules can be in two places at once, thanks to quantum physics. That's something that scientists have long known is theoretically true based on a few facts: Every particle or group of particles in the universe is also a wave... Continue Reading →
The search narrows for a mysterious form of matter predicted from Einstein's theory of special relativity. After more than a decade of looking, scientists at the world's largest particle collider believe that they are on the verge of finding it. But... Continue Reading →
