Ultrafast electrons and lasers reveal unexpectedly strong radiation signals in common semiconductorsDetecting radiation is key to technologies ranging from particle accelerators and scientific instruments to medical imaging and security screening. But current detectors must often make trade-offs, providing signals that are strong but slow or fast but weak. The trade-off between signal strength and speed can limit precision detection. Go to Source An international collaboration of researchers has used ANSTO’s facilities to uncover new properties of one of the most fundamental everyday materials, water, and answer an important scientific question. The findings, published in Nature Communications, have practical implications for understanding water at very low temperatures. The findings are relevant to cryopreservation of biological materials, food-freezing technologies […] A new study has demonstrated that it is possible to make a network of atoms and photons that could improve how artificial intelligence stores and recalls memories. This network, called a quantum-optical spin glass, works as an associative memory, a form of AI that enables the recall of full memories from partial information—much like how […] The BESIII Collaboration, led by the Institute of High Energy Physics of the Chinese Academy of Sciences, has achieved the world’s most precise measurement of the electric dipole moment (EDM) of the Lambda (Λ) hyperon using quantum-entangled Λ–anti-Λ pairs produced in J/ψ decays. The result improves the experimental sensitivity by about three orders of magnitude […] Research means asking questions of the universe. For centuries, clever minds have advanced science by devising ingenious experiments designed so their results reveal something about the laws of nature as clearly and unambiguously as possible. Go to Source A new study led by surfing scientists at the Scripps Institution of Oceanography at UC San Diego revealed the physical relationships underlying a pattern familiar to generations of surfers. Go to Source Researchers from MIT have designed a new qubit architecture that enables qubits to interact with each other much more quickly while remaining very stable. This advance could someday help scientists build practical quantum computers that can run long, complex algorithms with high accuracy. Go to Source The hidden world of quantum mechanics exists at scales many orders of magnitude smaller than living organisms, yet scientists have long theorized that quantum effects play an important role in biology. Birds’ ability to sense magnetic fields during migration is one of the best-known mysteries in this field, with leading theories suggesting that this sensing […] Heat, it turns out, has a memory. A cooling cup of coffee may not seem particularly thoughtful. At the scale of a kitchen, heat appears to follow a straightforward rule: it moves from warmer places to cooler ones. Leave the cup unattended long enough, and the disappointing result offers convincing evidence that this rule works. […] Using an engineered metasurface that traps light, Cornell researchers have demonstrated a new way to generate strong static magnetic fields without using external magnets or magnetic materials—an approach that could advance spintronics, quantum and photonic computing, and data storage. Go to Source What happens when a superconductor becomes so thin that electrons can no longer behave as if they were moving through an ordinary three-dimensional piece of metal? This question has been at the center of my recent work on quantum confinement in metallic films. Over the past few years, I have been developing this line of […] Inside some fusion energy systems, particles hotter than the core of the sun can become unruly in a few thousandths of a second, far faster than any human operator can react. A new software framework developed by researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University hands those […] An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted effect of gravity on a falling quantum object for the first time. The result shows that a fundamental principle at the heart of Einstein’s theory of gravity remains consistent with the behavior of matter in the quantum world. The study, […] Neutrinos are pervasive yet intangible particles that permeate the universe, streaming through whole planets, stars and our bodies by the trillions each second. The elementary particles are often described as “ghostly” for their near-zero mass and elusive nature, as they have very little interaction with normal matter. Go to Source The weak equivalence principle (WEP) is central to Einstein’s general relativity. It posits that gravity must accelerate everything equally, regardless of what it is made from. For the first time, a team led by Ming-Sheng Zhan at the Wuhan Institute of Physics and Mathematics has tested the principle using clouds of continuously free-falling atoms aboard […] |
