Sunlight has a major influence on chemical processes. Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of the substances present in the air. A well-known example is the formation of ground-level ozone when UV light hits nitrogen...
Nobel prize-winning physicist Peter Higgs, who proposed the existence of the so-called "God particle" that helped explain how matter formed after the Big Bang, has died at age 94, the University of Edinburgh said Tuesday....
A team has taken the first atomic-resolution images and demonstrated electrical control of a chiral interface state -- an exotic quantum phenomenon that could help researchers advance quantum computing and energy-efficient electronics....
A method based on CT (computed tomography)—a type of imaging that is widely used in hospitals—can help improve our understanding of CO2 storage, batteries, and processes in the body such as nutrient uptake....
A research team led by The Hong Kong University of Science and Technology (HKUST) and Tsinghua University has theoretically proposed a new mechanism of electrical 180° switching of Néel vector and experimentally realized it in antiferromagnetic materials with spin-splitting band structure featuring...
A research team has pioneered an innovative technique in ultra-high-resolution spectroscopy. Their breakthrough marks the world's first instance of electrically controlling polaritons—hybridized light-matter particles—at room temperature. The research has been published in Physical Review Letters....
Operating at CERN's Large Hadron Collider (LHC) since 2022, the FASER experiment is designed to search for extremely weakly interacting particles. Such particles are predicted by many theories beyond the Standard Model that are attempting to solve outstanding problems in physics such as the nature...
A new molecular test method helps to prove the authenticity of works of art. The new method could also help to make passwords secure against quantum computers....
The diffraction of light is a ubiquitous phenomenon in nature where waves spread out as they propagate. This spreading of light beams during propagation limits the efficient transmission of energy and information. Therefore, scientists have endeavored to suppress diffraction effects to better...
Researchers at the Large High Altitude Air Shower Observatory (LHAASO) have accurately measured the cosmic ray all-particle energy spectrum and the mean logarithmic mass in the range of 0.3–30 peta-electronvolts (PeV). They have also discovered an "elbow" feature in the mean logarithmic mass...
