The installed Beam Gas Curtain on the LHC. Credit: CERN / Maximilien Brice A novel beam diagnostic instrument developed by researchers in the University of Liverpool’s QUASAR Group has been approved for use in the Large Hadron Collider (LHC), the world’s most powerful particle accelerator. The new device, known as the Beam Gas Curtain (BGC)

Synergistically cooled Be⁺-HD⁺ ion crystal and molecular dynamics simulation. Credit: APM A research team from the Innovation Academy for Precision Measurement Science and Technology (APM) of the Chinese Academy of Sciences has made significant progress in precisely measuring the vibrational-rotational spectra of hydrogen molecular ions (HD⁺). The researchers prepared a Be⁺-HD⁺ two-component ion Coulomb crystal

Graphic illustrating the difference in energy between running a quantum clock (left: a single electron hopping between two nanoscale regions) and reading the ticks of the clock (right). The energy required to read the clock is roughly one billion times larger than the energy required to run the clock. Credit: Natalia Ares, Vivek Wadhia, Federico

Until now, physicists thought that all heavy nuclei deformed from spheres are elongated in one direction like rugby balls (top), but RIKEN researchers have shown that virtually all of such nuclei have triaxial symmetry with oval cross-sections like almonds (bottom).

The lecture was called “Is the end in sight for theoretical physics?” Hawking, who later became my Ph.D. supervisor, predicted that a theory of everything—uniting the clashing branches of general relativity, which describes the universe

AI illustration of the proposed experiment—Time-Resolved and Superradiantly Amplified Unruh Effect. Credit: Navdeep Arya Researchers from Stockholm University and the Indian Institute of Science Education and Research (IISER) Mohali have reported a practical way to spot one of physics’ strangest predictions: the Unruh effect, which says that an object speeding up (accelerating) would perceive empty

Credit: CC0 Public Domain The geometry of space, where physical laws unfold, may also hold answers to some of the deepest questions in fundamental physics. The very structure of spacetime might underlie every interaction in nature. A paper published in Nuclear Physics B, led by Richard Pincak, explores the idea that all fundamental forces and

The overall PhyE2E framework. Top: the training dataset was augmented with a large-scale synthetic dataset generated by an LLM. MLP, multilayer perceptron. Middle: a variable-interaction technique was integrated to decompose the original symbolic regression problem into simpler subproblems, referred to as D&C. An end-to-end model was trained to predict the target formula using observed data
