Multiple laser beamlets show better electron and ion acceleration
Jul 26, 2019 (SPX)
High-energy density physics is a field of study that deals with conditions much closer the chaotic moments immediately following the Big Bang than those commonl...
Physicists find first possible 3D quantum spin liquid
Jul 22, 2019 (SPX)
Despite the name, a quantum spin liquid is a solid material in which the weird property of quantum mechanics - entanglement - ensures a liquidlike magnetic stat...
New Measurement of Cosmic Expansion Rate Is Stuck in the Middle
Jul 17, 2019 (SPX)
Nearly a century ago, Carnegie astronomer Edwin Hubble discovered that the universe has been growing continuously since it exploded into being during the Big Ba...
New Measurement Adds to Mystery of Universe's Expansion Rate
Jul 17, 2019 (SPX)
Scientists have known for almost a century that the universe is expanding, meaning the distance between galaxies across the universe is becoming ever more vast ...
Could vacuum physics be revealed by laser-driven microbubble?
Jul 11, 2019 (SPX)
The quest for a better understanding of vacuum physics will lead to the elucidation of fundamental questions in modern physics, which is integral in unravelling...
