Fragmentation experiment reveals surprising fractured isospin symmetry

From the powdered wings of a butterfly to the icy spines of a snowflake, symmetry is a common feature in nature. This often even holds true down to the smallest bits of matter, which helps nuclear physicists ensure their measurements of the inhabitants of the subatomic world are accurate. The trick is knowing when something […]

Flavor symmetry of the high-energy world does not work as expected

In collisions of argon and scandium atomic nuclei, scientists from the international NA61/SHINE experiment have observed a clear anomaly indicative of a violation of one of the most important symmetries of the quark world: the approximate flavor symmetry between up and down quarks.

Innovative new detector to hunt for neutrinos

Technology is being pushed to its very limits. The upgrades to the Large Hadron Collider (LHC) at CERN slated for the next few years will increase data transfer rates beyond what the current neutrino detector for the FASER experiment can cope with, requiring it to be replaced by a new kind of more powerful detector. […]

ALICE detects the conversion of lead into gold at the Large Hadron Collider

In a paper published in Physical Review C, the ALICE collaboration reports measurements that quantify the transmutation of lead into gold in CERN’s Large Hadron Collider (LHC).

Topological polycrystal: A new approach to configurable, multiband topological photonic circuitry

Molding the flow of light—whether confined to localized regions or propagating in free space—remains crucial for modern integrated photonics. The advancement of the multi-channel, programmable optical waveguide and coupler arrays has enabled us to develop photonic integrated circuits (PICs) as a viable alternative to electronic ones, overcoming limitations in processing speed, bandwidth, and efficiency across […]

Q&A: What will it take to bring fusion energy to the US power grid?

Arianna Gleason is an award-winning scientist at the Department of Energy’s SLAC National Accelerator Laboratory who studies matter in its most extreme forms—from roiling magma in the center of our planet to the conditions inside the heart of distant stars. During Fusion Energy Week, Gleason discussed the current state of fusion energy research and how […]

Turning non-magnetic materials magnetic with atomically thin films

The rules about magnetic order may need to be rewritten. Researchers have discovered that chromium selenide (Cr2Se3)—traditionally non-magnetic in bulk form—transforms into a magnetic material when reduced to atomically thin layers. This finding contradicts previous theoretical predictions, and opens new possibilities for spintronics applications. This could lead to faster, smaller, and more efficient electronic components […]

Eggs less likely to crack when dropped side-on, research reveals

Eggs are less likely to crack when dropped on their side than when dropped vertically, finds research published in Communications Physics. Controlled trials simulating the “egg drop challenge,” a common classroom science experiment, found that the shell of an egg can better withstand an impact when dropped side-on.

A scalable approach to distill quantum features from higher-dimensional entanglement

The operation of quantum technologies relies on the reliable realization and control of quantum states, particularly entanglement. In the context of quantum physics, entanglement entails a connection between particles, whereby measuring one determines the result of measuring the other even when they are distant from each other, and in a way that defies any intuitive […]

Physicists propose a new route by which neutrinos can be produced

Buried deep in the ice in the Antarctic are “eyes” that can see elementary particles called neutrinos, and what they’ve observed is puzzling scientists: a remarkably strong neutrino signal accompanied by a surprisingly weak gamma-ray emission in the galaxy NGC 1068, also known as the Squid galaxy.

New microwave-to-optical transducer uses rare-earth ions for efficient quantum signal conversion

Quantum technologies, which leverage quantum mechanical effects to process information, could outperform their classical counterparts in some complex and advanced tasks. The development and real-world deployment of these technologies partly relies on the ability to transfer information between different types of quantum systems effectively.

Shortcut in ‘magnetic bottles’ design offers an answer to a complex 70-year-old fusion challenge

Abundant, low-cost, clean energy—the envisioned result if scientists and engineers can successfully produce a reliable method of generating and sustaining fusion energy—has taken one step closer to reality, as a team of researchers from the University of Texas at Austin, Los Alamos National Laboratory and Type One Energy Group has solved a longstanding problem in […]

Scientists edge closer to affordable superconductors: Novel materials could eventually power electric vehicles and more

Imagine a world in which free-floating electric vehicles charge wirelessly as they glide down highways, laptops are hundreds of times more powerful, and clean energy flows in limitless supply.

Unlocking a new class of materials with origami

Origami—the Japanese art of folding paper—could be the next frontier in innovative materials. Practiced in Japan since the early 1600s, origami involves combining simple folding techniques to create intricate designs. Now, Georgia Tech researchers are leveraging the technique as the foundation for next-generation materials that can both act as a solid and predictably deform, “folding” […]

Ultrafast spin-polarized current pulses measured in magnetic layers for the first time

An international team has succeeded at BESSY II for the first time to elucidate how ultrafast spin-polarized current pulses can be characterized by measuring the ultrafast demagnetization in a magnetic layer system within the first hundreds of femtoseconds.
