Physicists at CERN report that they've detected evidence of a rare meson particle decay (B⁰→ µ⁺µ⁻) that occurs when the meson's beauty quark annihilates with a down-type quark. The pair decays into a muon and antimuon, which are particles similar to electrons. Because evidence for this decay helps test theoretical predictions from the Standard Model, physicists have been waiting for it since 1984, when it was first theorized.
Newton's theory of gravity has described the tides accurately for centuries. But could a tiny trace of Einstein's general relativity also be hidden in them? In a new study, a mathematician at Freie Universität Berlin has outlined how a targeted approach could be used to search for effects of this nature.
Scientists have discovered how to reprogram the internal structure of glass using a special molecule that rearranges chemical bonds while lowering the melting temperature. The breakthrough could unlock entirely new glass materials with precisely controlled magnetic and optical properties, opening possibilities for advanced electronics, sensors, and other technologies.
In the theoretical study of proton-nucleus collisions, the colliding projectiles can be described as streams of color charges moving along their respective trajectories. These color charges couple to gluons, which then produce the particles that are observed in the final state (gluons and quarks, which eventually produce hadrons).
The principle "Work smarter, not harder!" apparently also applies to controlling quantum materials with light. Many of their fascinating properties depend on how the atoms are arranged in the crystal. Ultrashort laser pulses can be used to alter these structures in a targeted way—the light first excites electrons, whose changed energy and dynamics exert forces on the atomic nuclei and can thereby set the atoms in motion. Such processes unfold within femtoseconds, a millionth of a billi
A recent study published in Nature Electronics and carried out by researchers from nanoGUNE's Quantum Hardware research group, Quantum Motion, London Center for Nanotechnology, Imperial College London and the University of Cambridge introduces a new superinductor created within a silicon integrated circuit fabricated in a commercial complementary metal–oxide–semiconductor (CMOS) process.
Every time someone picks up a call, the phone does a quiet bit of translation. Incoming radio signals are converted into tiny sound waves that ripple across chips before being turned back into data.
MIT scientists have challenged two decades of conventional thinking by discovering that flexible molecular connections, rather than rigid ones, can unlock entirely new ways to arrange nanoparticles. The breakthrough could lead to a new generation of designer materials with unusual properties and applications in electronics, medicine, and energy.
For nearly 90 years, scientists believed magnetism fell into just two categories, but researchers have now confirmed a remarkable third type called altermagnetism. Using specialized X-rays, they uncovered a unique magnetic signature that proves these materials behave differently from conventional magnets. Altermagnets combine stability with the ability to efficiently carry information, potentially overcoming major limitations in today's electronics. The discovery could lead to faster comput
Are the laws of physics truly the same everywhere in the universe? This fundamental principle, known as Lorentz invariance, lies at the heart of Einstein's theory of relativity. Yet some theories that seek to reconcile gravity with quantum physics suggest that it might not always hold. To investigate this possibility, researchers from the international KM3NeT collaboration analyzed 5,828 atmospheric neutrino candidate events detected by KM3NeT/ORCA, a neutrino telescope located deep in the
Imagine shuffling a deck of cards where some of the cards are fading just because of the way they interact with the external environment as you shuffle them. Your job is to figure out the interplay between the shuffling, or "imposed randomness," due to the way you shuffle your cards and how that relates to the fading as cards are exposed to the external environment.
Researchers from the Faculty of Physics at the University of Warsaw, the Military University of Technology (Poland), IBM Research Zurich and the French National Centre for Scientific Research (CNRS) have observed a new quantum state of matter known as a supersolid in an exciton-polariton Bose-Einstein condensate. Remarkably, the phenomenon occurs not at temperatures close to absolute zero, but at room temperature. The results have been published in Science Advances.
Researchers from ICMAB-CSIC, the Politecnico di Milano and Université de Liège have adapted a direct laser writing technique that allows them to "draw" superconducting properties in a material. The result is a new way to locally program the behavior of a superconductor, tuning it from a fully superconducting state to an insulating one with extraordinary precision.
Physicists have found evidence of a particle decay so rare that it is expected to occur only around once in every 10 billion "beauty" particles. The result, from the upgraded LHCb experiment at CERN's Large Hadron Collider (LHC), follows a search spanning more than 40 years and brings physicists closer to exploring the "Zeptoverse"—an unexplored world that exists at distances of a billionth of a trillionth of a meter, or a "zeptometer," where new particles and
Stanford engineers and colleagues designed a chip that can take a muddled mixture of light from multiple lasers and output clean beams of light. It's the first time researchers have demonstrated a device that can take in mixed, or partially coherent, light and sort its photons into a clear set of separate beams.
Scientists at CERN's Large Hadron Collider have uncovered compelling new evidence that even relatively small atomic collisions can recreate the extraordinary state of matter that filled the universe moments after the Big Bang. Known as quark-gluon plasma, this exotic substance forms at temperatures more than 100,000 times hotter than the center of the Sun, causing ordinary particles to break apart into their fundamental building blocks.
Scientists have discovered a possible loophole in the laws that normally prevent black holes from splitting apart, suggesting that extremely fast-spinning black holes might divide into two. The surprising finding raises the possibility of an entirely new black hole phenomenon that future telescopes could potentially detect.
A research team wanted to better understand how the forces between particles inside a material change. They discovered that by confining one-dimensional classical spin chains inside a mirror box cavity with light, they could force these magnetic particles to organize and undergo a phase transition. Their work provides the simplest exactly solvable examples showing that light can create new phase transitions with materials.
One approach to making information storage in quantum computing less prone to errors is known as topological quantum computing. It relies on special quantum states that are expected to be more resistant to local disturbances.
Quantum computers rely on qubits as their units of information. To connect them into a larger network across long distances, they need to transmit quantum information using light.
