A mysterious magnetic material once thought to host an exotic “quantum spin liquid” has turned out to be something entirely different—and possibly just as intriguing. Scientists studying cerium magnesium hexalluminate found it showed the hallmark signs of this elusive quantum state, like a lack of magnetic order and a spread of energy states. But after closer inspection using neutron experiments, they discovered the behavior came from a delicate tug-of-war between two opposing magnetic forces.

This unusual “superionic” structure could reshape how heat and electricity flow inside these distant worlds, potentially helping explain their mysterious magnetic fields.

Spintronics are devices that operate leveraging the spin, an intrinsic form of angular momentum, of electrons. The ability to switch magnetic states is central to the functioning of these devices, as it ultimately allows them to represent binary digits (i.e., "0" and "1") when processing or storing information.

A quantum spin liquid is a phase of matter in which the magnetic moments in a material do not align or freeze, even at temperatures close to absolute zero (i.e., at 0 K).

Composed of five or more elements in nearly equal amounts, high-entropy alloys (HEAs) have emerged as promising catalysts due to their compositionally complex surfaces that can accelerate chemical reactions. Until now, scientists have not been able to precisely engineer these surface structures at the nanoscale, making it difficult to study how particle shape influences catalytic performance. Now, a study led by Northwestern University professors Chad A. Mirkin and Christopher M. Wolverton has solved that problem. The research is published in the Journal of the American Chemical Society.

Today, I want to walk you through a deceptively simple innovation from the lab at Loughborough University (PI: Prof Marco Peccianti): what happens when we decorate a spintronic heterostructure with a sparse layer of plasmonic nanoparticles?

This could allow chemical and materials science processes to be simulated more accurately in the future, potentially accelerating the development of new drugs, more efficient batteries, and more sustainable materials.

A new theoretical study finds shorter laser pulses achieve higher quantum efficiency for photoemission from a solid surface without increasing power or intensity. Using light to knock electrons loose from a surface—known as photoemission—may soon be achievable more easily in smaller labs with smaller lasers. Shortening the length of a laser pulse can increase the emitted electrons by several orders of magnitude without increasing the laser intensity or power, according to a University of Michigan Engineering study.

In the quirky quantum world, particles can be affected by forces that they never directly encounter. A classic example is the Aharonov–Bohm (AB) effect, where electrons are affected by a magnetic field, despite not passing through it. Although predicted in 1959, it took more than two decades to confirm this effect experimentally, as the specific changes to the electrons' wave properties could only be inferred indirectly, and with great difficulty. Now, physicists from the Okinawa Institute of Science and Technology (OIST), in collaboration with the University of Oslo and Universidad Adolfo Ibáñez, have used a classical fluid analog that mimics and extends the AB effect using a simple platform: a water tank.

Picture two materials sandwiched together. The boundary between them may appear flat, but, in reality, it is full of tiny bumps and dents. Suddenly, the materials are hit with a shockwave. If that wave hits a bump in the material interface, it slows down. If it hits a dent, it accelerates forward. This imbalance creates fast, narrow jets of material—called the Richtmyer-Meshkov (RM) instability.

A surprising breakthrough in physics could reshape the future of computing by tapping into a strange, previously untapped property of matter. Scientists have shown that tiny atomic vibrations—called chiral phonons—can directly transfer motion to electrons, allowing them to carry information without magnets, batteries, or even electricity. This opens the door to a new field known as orbitronics, where data is processed using the orbital motion of electrons instead of traditional charge or spin.

Researchers in the UC Santa Barbara Materials Department have uncovered the elusive quantum mechanism by which energetic electrons break chemical bonds inside microelectronic devices—a detrimental process that slowly degrades performance over time.

Focusing on Cygnus X-1, one of the first known black holes, they measured jets blasting out with the energy of 10,000 Suns and moving at half the speed of light. By watching these jets get pushed and bent by the fierce stellar winds of a nearby supergiant star, researchers could calculate their true power for the first time.

Researchers have shown that blending quantum computing with AI can dramatically improve predictions of complex, chaotic systems.

In 2014, a strange cloudy object called G2 made a close approach to Sagittarius A*, (Sag A*) the supermassive black hole at the heart of the Milky Way Galaxy. Astronomers were pretty excited, partly because they thought it might get torn apart by Sag A*'s intense gravitational pull. That didn't happen, and the event was a cosmic fizzle. Instead, G2 skipped around the black hole. Various observations showed that it wasn't just a gas cloud. It was likely a dusty protostellar object encased in a dusty cloud. Or perhaps several merged stars. But, it survived the flyby and continued on a shortened orbit.

An AI model informed by calculations from a quantum computer can better predict the behavior of a complex physical system over the long term than current best models that use only conventional computers, according to a new study led by UCL (University College London) researchers.

A new quantum sensing approach could dramatically improve how scientists measure low-frequency electric fields, a task that has long been limited by bulky setups and blurry resolution. Instead of relying on traditional vapor-cell methods, researchers developed a system using chains of highly sensitive Rydberg atoms that respond collectively to electric fields. As the field shifts, it subtly changes how these atoms interact, allowing both the strength and direction of the field to be decoded with remarkable precision.

The time had come to open the envelope, but Stephan Schlamminger, a physicist at the National Institute of Standards and Technology (NIST), wasn't sure he wanted to know the secret number that lay inside. For the past 10 years, Schlamminger had spent most of his working hours trying to measure a single quantity, known as the universal gravitational constant, which determines the strength of gravity everywhere in the universe. The secret number would allow Schlamminger to unscramble his data and get his answer.

Author(s): Danat Issa, Beverly Lowell, Jonatan Jacquemin-Ide, Matthew Liska, and Alexander TchekhovskoyLaunching jets from collapsar black holes requires strong magnetic field and rapid rotation. However, strong fields can spin down the collapsar black holes before the jet can be launched. In this work, the authors study the effect of neutrino cooling on this jet launching process. They show that neutrino cooled disks can continue to feed angular momentum to the black hole without the opposing spin-down effect that comes from general mass accretion. Thus, the spin of the black hole remains sufficient high to launch a jet from a collapsar environment to produce a long gamma-ray burst. [Phys. Rev. D 113, 083020] Published Wed Apr 15, 2026

In our simulations that include surface tension effects, we find that breaking inception occurs when the local interface angle exceeds 60°; a value twice that reported in previous studies without surface tension. We explore this result in the context of the commonly utilized kinematic inception parameter and show that these two indicators of breaking inception are related through the relative flux of energy into the wave crest.

How do organic solar cells work on the inside? The answer lies in structures far too small to see—and difficult to access even with advanced techniques. So far, researchers have relied mainly on X-ray methods to understand how molecules are arranged within these materials and how this order can be optimized for high efficiency. While powerful, X-rays provide only a spatially averaged picture. Electrons, in contrast, offer a local view at the nanoscale, revealing both structure and chemical composition.

A growing mystery in astronomy is the presence of gargantuan black holes—some weighing as much as a billion suns—existing less than a billion years after the Big Bang. According to the standard theory of black hole formation, these black holes simply should not have had enough time to grow so large. A study led by University of California, Riverside graduate student Yash Aggarwal shows that dark matter decays could be the key to understanding the origin of these cosmic behemoths. Published in the Journal of Cosmology and Astroparticle Physics, the research shows that the energy released from dark matter decay could alter the chemistry of early galaxies enough to cause some of them to directly collapse into black holes rather than forming stars.
