Researchers test key neutrino model at the Large Hadron Collider

The CMS collaboration at the Large Hadron Collider (LHC) has carried out a new test on a model that was developed to explain the tiny mass of neutrinos. They are electrically neutral particles that change type as they travel through space. The particles cannot be...

In a sea of magic angles, ‘twistons’ keep electrons flowing through three layers of graphene

In the quantum materials community, the discovery of superconductivity in two ever-so-slightly twisted layers of graphene made waves a few years ago. Scientists had discovered a simple device to study the resistance-free flow of electricity, with just two atom-thin sheets of carbon. The angle...

Shedding new light on controlling material properties in solid-layered perovskite

Materials scientists will soon be able to control material properties with light. Kyoto University and Kurume Institute of Technology researchers have discovered a scaling law that determines high-order harmonic generation in the solid-layered perovskite material named Ca2RuO4. High-order harmonic generation is a nonlinear optical phenomenon....

Thermal electrons play key role in determining emissions from gamma-ray-burst afterglows

The presence of unusually energetic gamma rays seen in some afterglows from intense gamma-ray bursts (GRBs) could be explained by a new mathematical model developed by RIKEN researchers. This finding could help to shed light on the origin of GRBs. A GRB is a spectacular...

Ultrathin films of cesium antimonide used to make more efficient photocathodes

Scientists developed an ultrathin film of cesium antimonide that can be used as a highly efficient photocathode. The study was published in the journal Physical Review Letters. Scientists describes their approach to create the photocathode and how it performed when compared to conventional photocathodes. A...

Engineering quantum states in solids using light

POSTECH researchers have developed a platform. It can control the properties of solid materials with light and measure them. Scientists recognised for developing a platform to control and measure the properties of materials in various ways with light. The study was published in the journal...
