A study co-led by ICN2 reveals that ice is a flexoelectric material, meaning it can produce electricity when unevenly deformed. Published in Nature Physics, this discovery could have major technological implications while also shedding light on natural phenomena such as lightning.

Frozen water is one of the most abundant substances on Earth. It is found in glaciers, on mountain peaks and in polar ice caps. Although it is a well-known material, studying its properties continues to yield fascinating results.

An international study involving ICN2, at the UAB campus, Xi’an Jiaotong University (Xi’an) and Stony Brook University (New York), has shown for the first time that ordinary ice is a flexoelectric material.

In other words, it can generate electricity when subjected to mecha...

New research from the University of St Andrews paves the way for holographic technology, with the potential to transform smartdevices, communication, gaming and entertainment.

In a study published in Light: Science & Applications, researchers from the School of Physics and Astronomy created a new optoelectronic device from the combined use of holographic metasurfaces (HMs) and organic light-emitting diodes (OLEDs).

Until now, holograms have been created using lasers. However, researchers have found that using OLEDs and HMs gives a simpler and more compact approach that is potentially cheaper and easier to apply, overcoming the main barriers to hologram technology being used more widely.

Organic light-emitting diodes are thin film devices widely used to make the colored pixels...

Scientists at CERN’s ATLAS experiment have uncovered compelling evidence of Higgs bosons decaying into muons, an incredibly rare event that could deepen our understanding of how particles acquire mass. They also sharpened their ability to detect the even rarer Higgs decay into a Z boson and a photon—a process that might reveal hidden physics beyond the Standard Model.

The ATLAS Collaboration finds evidence of Higgs-boson decays to muons and improves sensitivity to Higgs-boson decays to a Z boson and a photon.

Since the discovery of the Higgs boson in 2012, physicists have made major strides in exploring its properties...

While quantum computers are already being used for research in chemistry, material science, and data security, most are still too small to be useful for large-scale applications. A study led by researchers at the University of California, Riverside, now shows how “scalable” quantum architectures—systems made up of many small chips working together as one powerful unit—can be made.

In the study, published as a letter in the journal Physical Review A, the researchers simulated realistic architectures and found that even imperfect links between quantum chips can still produce a functioning, fault-tolerant quantum system—a leap forward in scaling quantum hardware.

“Our work isn’t about inventing a new chip,” said Mohamed A...
