In 1956, theoretical physicist David Pines predicted that electrons in a solid could form a composite particle called a demon. It's eluded detection since its prediction....until now.
In a banner year for Los Alamos National Laboratory in the competition for Department of Energy Early Career Research Awards, four scientists nabbed multiyear funding for their projects.
Four scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have been selected by DOE's Office of Science to receive significant funding through its Early Career Research Program.
At particle accelerator facilities around the world, scientists rely on powerful X-rays to reveal the structure and behavior of atoms and molecules. Now, researchers from the Department of Energy’s SLAC National Accelerator Laboratory have calculated how to make X-ray pulses at X-ray free-electron lasers (XFEL) even brighter and more reliable by building a special cavity chamber and diamond mirrors around an XFEL.
A collaboration of nuclear theorists has used supercomputers to predict the spatial distributions of charges, momentum, and other properties of "up" and "down" quarks within protons. The calculations show that the up quark is more symmetrically distributed and spread over a smaller distance than the down quark.
PNNL scientists design a highly sensitive neutrino detector for the Deep Underground Neutrino Experiment.
Scientists working on the Dark SRF experiment at the U.S. Department of Energy’s Fermi National Accelerator Laboratory have demonstrated unprecedented sensitivity in an experimental setup used to search for theorized particles called dark photons.
Today, the U.S. Department of Energy (DOE) announced the release of a Draft Request for Proposals (RFP) for the selection of a management and operating (M&O) contractor for the Fermi National Accelerator Laboratory (FNAL).
Allison Zec has been awarded the 2022 JSA Thesis Prize for recounting experiments that achieved the world record in the precise measurement of an electron beam’s polarization. Since 1999, the prize has been awarded to the top doctoral dissertation on research related to Jefferson Lab science. The prize is funded by the JSA Initiatives Fund program, which supports programs, initiatives and activities that further the scientific outreach and promote the science, education and technology missions of Jefferson Lab, and which benefit the laboratory’s scientific user community.
The cryogenic plant, to be installed a mile underground, will provide the cooling for two large liquid-argon neutrino detectors for the international Deep Underground Neutrino Experiment.
In Applied Physics Letters, researchers report achieving self-sustaining and long-term levitation of millimeter-sized droplets of several different liquids without any external forces. To get the droplets to levitate, they use solutocapillary convection, which occurs when a surface tension gradient is formed by nonuniform distribution of vapor molecules from the droplet at the pool surface.
Researchers recently reviewed the current standard procedure to determine the nuclear weak distribution, which describes the distribution of active protons in a nucleus. The new analysis found significant differences with previous model-based determinations of the nuclear weak distribution. The results provide a partial explanation for a discrepancy between predictions from particle physics theory and experimental measurement of a fundamental quantity.
A research group led by Associate Professor Jing Li from the School of Physics at Peking University published an article in Science Bulletin entitled "The shift of decadal trend in Middle East dust activities attributed to North Tropical Atlantic variability."
In chemistry, a molecule or ion is said to be chiral if it cannot be superposed on to its mirror image by any combination of rotations, translations, or conformational changes. A chiral molecule or ion exists in two forms, called enantiomers, that are mirror images of each other; they are often distinguished as either ‘right-handed’ or ‘left-handed’ by their absolute configuration. Enantiomers exhibit similar physical and chemical properties, except when interacting with polarized light and reacting with other chiral compounds, respectively.
Earth is constantly being struck by cosmic particles. High-energy muons can easily penetrate several meters of steel or concrete. A team at the German independent research institute Helmholtz-Zentrum Dresden-Rossendorf (HZDR) seeks to harness the potential of this unavoidable background radiation to view the interior of industrial facilities or structures.
New measurements of how particles flow from collisions of different types of particles at the Relativistic Heavy Ion Collider (RHIC) have provided new insights into the origin of the shape of hot specks of matter generated in these collisions. The results may lead to a deeper understanding of the properties and dynamics of this form of matter, known as a quark-gluon plasma (QGP).
The recent tragic loss of the Titan submersible in the depths of the North Atlantic has brought the fascinating (and very dangerous) world of Oceanography and Marine Science to the forefront. Below are some recent stories that have been added to the Marine Science channel on Newswise, including expert commentary on the Titan submersible.
Supported by his Early Career Research Program award, physicist Junjie Zhu’s work at the CERN Large Hadron Collider led to the first-ever evidence of two rare but important physics processes. These interactions produce the particles responsible for nuclear decay.
Electrons inside crystals interact closely with phonons, defined as the discrete unit of crystal vibrations.
New research findings published in Physical Review Letters provides theorists with new input for calculating how much gluons—the gluelike particles that hold quarks together within protons and neutrons—contribute to a proton’s spin.
