Watching quantum behavior in action: MagnetoARPES reveals time-reversal symmetry breaking in a kagome superconductor

Electron movement and structures described in quantum physics allow researchers to better understand how and why materials like superconductors behave as they do. Rice University researchers Jianwei Huang and Ming Yi have developed a new capability, magnetoARPES, building on angle-resolved photoemission spectroscopy (ARPES) that allows researchers to study quantum behaviors they have been unable to resolve using ARPES alone. The work has been published in Nature Physics.

Oval orbit casts new light on black hole–neutron star mergers

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an oval path rather than a perfect circle just before they merged. This discovery challenges long-standing assumptions about how these cosmic pairs form and evolve.

How jagged moon dust could support future astronauts

Lunar dust can be a pain—but it’s also literally the ground we will have to traverse if we are ever to have a permanent human settlement on the moon. In that specific use case, its clingy, jagged, staticky properties can actually be an advantage, according to a new paper recently published in Research from scientists at Beihang University, who analyzed the mechanical properties of samples returned by the Chang’e 6 mission to the far side of the moon.

Ultrafast computing: Light-driven logic tops 10 terahertz in WS₂

The future for our computers will literally be at the speed of light. Extremely short light pulses can perform ultrafast logical operations: these are the findings of a study recently published in the journal Nature Photonics. The study represents an important step toward developing a new generation of information processing technologies, potentially hundreds of times faster than what we have at present.

Chemical shifts help track molecules breaking apart in real time

When molecules fall apart, their electric charge doesn’t stay put—it rearranges as bonds stretch and break. An international team of scientists has now tracked these ultrafast changes in the small molecule fluoromethane (CH₃F). It was the first time that the Small Quantum Systems (SQS) instrument at European XFEL could deliver detailed insights into transient states during chemical reactions. The research is published in the journal Physical Review X.

Unexpected magnetic response in gold and silver atomic contacts contradicts previous theoretical predictions

Researchers from the Department of Physics and the University Institute of Materials at the University of Alicante (UA) and the Low Temperature and High Magnetic Field Laboratory at the Autonomous University of Madrid (UAM) have succeeded in measuring, for the first time, the electrical conductance of gold and silver atomic contacts subjected to extreme magnetic fields of up to 20 teslas, an intensity equivalent to 400,000 times Earth’s magnetic field.

NASA finds extreme star collision in unlikely spot

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an environment like this before—and it may help solve two outstanding cosmic mysteries. A paper describing these results is forthcoming in The Astrophysical Journal Letters and currently available on the arXiv preprint server.

3D-printed photonic lanterns combine up to 37 multimode lasers into one fiber

Researchers have developed a microscopic 3D-printed optical device that can efficiently combine light from dozens of small semiconductor lasers into a single multimode optical fiber with very low loss. The team demonstrated photonic lanterns that multiplex 7, 19, and 37 multimode VCSEL lasers directly into a fiber while preserving brightness and easing alignment constraints. By enabling scalable incoherent beam combining of many multimode lasers, the technology could simplify and improve high-power laser systems, optical communications, and other photonic applications where efficiently delivering large optical power through fibers is critical.

A new model defines an upper limit to planetary radiation belt intensity

We all know that stars radiate light and much more. But radiation belts can also surround many other celestial bodies, such as planets. These belts do not generate particles themselves—the belts receive them from nearby stars—but they accelerate the speed of particles in a way that has remained elusive.

Scientists control ‘free-flowing’ electric currents with light

By controlling magnetic fields using light, a team of researchers led by NTU scientists has solved a long-standing challenge to precisely direct electric currents produced by quantum materials. Their findings unlock new avenues for controlling the flow of electricity through such materials and could herald the age of energy-efficient quantum computing devices. The research is published in Nature in January.

New exoplanet survey method finds high rates of closely orbiting planets

Up until now, exoplanet surveys have mostly focused on nearby, bright stars that are sun-like or are red dwarfs, which are known to frequently host planets. While astronomers have discovered thousands of planets this way, a new study, published in the Monthly Notices of the Royal Astronomical Society, seems to have found a more efficient way of detecting planets that orbit close to their stars.

Astrophysicists trace the origin of valuable metals in space, from colliding stars to merging galaxies

Billions of light years away in a remote part of the universe, two neutron stars—the ultradense remnants of dead stars—collided. The catastrophic cosmic event sent light and particles, including a sudden flash of gamma rays, streaming through the universe. These gamma rays traveled for 8.5 billion years before reaching Earth.
