Excitons, encountered in technologies like solar cells and TVs, are quasiparticles formed by an electron and a positively charged "hole," moving together in a semiconductor. Created when an electron ...

The passing gravitational waves “stretch or contract the universe by around 20 meters [about 65 feet] or so,” says Matthew ...

Protons are far from simple particles — they are swirling cauldrons of quarks, gluons, and quantum entanglement. Scientists ...

Physicists measured how readily a current of electron pairs flows through 'magic-angle' graphene, a major step toward understanding how this unusual material superconducts. By determining how readily ...
