New Finding of Particle Physics May Help to Explain the Absence of Antimatter
In the Standard Model of particle physics, there is almost no difference between matter and antimatter. But there is an abundance of evidence that our observable universe is made up only of matter – if there was any antimatter, it would annihilate with nearby matter to produce very high intensity gamma radiation, which has not…
Hydrogen Ions Enable Scientists to Control Magnetic Properties in Materials
Hydrogen ions may hold the key to enabling spintronics to produce memory, computing and sensing devices that consume less power than current versions and overcome some of the limitations stymying progress. Researchers from the Massachusetts Institute of Technology and the U.S. Department of Energy’s Brookhaven National Laboratory have found a way to control the magnetism…
Researchers Look Deeper Into Mirrored Molecules
Scientists have developed a new method to examine the mirror images of several molecules that exist in nature. A team of researchers from the Deutsches Elektronen-Synchrotron, Universität Hamburg and University College London has developed a technique to develop custom-made mirror molecules that will enable them to gain new insight into the inner workings of nature…
Unified Theory Explains Two Characteristic Features of Frustrated Magnets
For the first time, physicists present a unified theory explaining two characteristic features of frustrated magnets and why they’re often seen together. When physicists send neutrons shooting through a frustrated magnet, the particles spray out the other side in signature patterns. The designs appear because, even at low temperatures, atoms in a frustrated metal oscillate…

Scientists Shuffle the Deck to Create Materials With New Quantum Behaviors
Flow Units: Dynamic Defects in Metallic Glasses
In a crystal, structural defects such as dislocations or twins are well defined and largely determine the mechanical and other properties. These defects can be easily identified as the broken long-range atomic order. However, the lack of a periodic microstructure makes the searching of similar structural defects a difficult task in amorphous materials. Recent studies…
Scientists to Track the Reaction of Crystals to the Electric Field
The international scientific team, which included the researchers and alumni of Peter the Great St. Petersburg Polytechnic University (SPbPU) developed a new method for measuring the response of crystals on the electric field. The results a collaborative research done at the European Synchrotron Radiation Facility (ESRF) were published in the Journal of Applied Crystallography and appeared on the cover of…
Magnetic Pumping Pushes Plasma Particles to High Energies
Disorder Plays a Key Role in Phase Transitions of Materials
Phase transitions are common occurrences that dramatically change the properties of a material, the most familiar being the solid-liquid-gas transition in water. Each phase corresponds to a new arrangement of the atoms within the material, which dictate the properties of the substance. While these arrangements can be easily studied in each phase individually, it is…
Army Scientist Seeks Enhanced Soldier Systems Through Quantum Research
Researchers at the U.S. Army Research Laboratory and the Joint Quantum Institute have created a pristine quantum light source that has the potential to lead to more secure communications and enhanced sensing capabilities for Soldiers. ARL’s Dr. Elizabeth Goldschmidt and JQI’s Dr. Sunil Mittal and Prof. Mohammad Hafezi discuss this research in their paper titled…
New Tech Delivers High-Tech Film That Blocks Electromagnetic Interference
Enhancing Precision for MRIs
Researchers from the Michigan Technological University have made high-frequency MRIs more precise by creating a better, more uniform magnetic field. The team found that radio frequency probes with structures inspired by microstrip patch antennas (MPA) would increase the MRI resolution in high-frequency MRI machines, when compared to the conventional surface coils that are commonly used…
Shielded Quantum Bits
A theoretical concept to realize quantum information processing has been developed by Professor Guido Burkard and his team of physicists at the University of Konstanz. The researchers have found ways to shield electric and magnetic noise for a short time. This will make it possible to use spins as memory for quantum computers, as the…
Scientists Present Ideas for Next-Gen Accelerator Experiments
When the FACET-II facility at the Department of Energy’s SLAC National Accelerator Laboratory opens its doors to scientists from around the world in early 2020, it’ll offer exceptional conditions for experiments that aim to revolutionize the field of accelerator physics. With powerful beams of electrons 100 to 1,000 times brighter than its predecessor, the upgrade to…
Ferroelectricity–an 80-Year-Old Mystery Solved
Only now in 2018 have researchers successfully demonstrated that hypothetical ‘particles’ that were proposed by Franz Preisach in 1935 actually exist. In an article published in Nature Communications, scientists from the universities in Linköping and Eindhoven show why ferroelectric materials act as they do. Ferroelectricity is the lesser-known twin of ferromagnetism. Iron, cobalt and nickel…
Surprise Finding: Discovering a Previously Unknown Role for a Source of Magnetic Fields
Magnetic forces ripple throughout the universe, from the fields surrounding planets to the gasses filling galaxies, and can be launched by a phenomenon called the Biermann battery effect. Now scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have found that this phenomenon may not only generate magnetic fields, but can…

Scientific Research Will Help to Understand the Origin of Life in the Universe
Until now, in the scientific community there has been the prevailing view that thermal processes associated exclusively with the combustion and high-temperature processing of organic raw materials such as oil, coal, wood, garbage, food, tobacco underpin the formation of PAHs. However, the scientists from Samara University, together with their colleagues from the University of Hawaii,…
