Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current.

Something genuinely strange has just happened in fundamental physics: an underground neutrino telescope in the Mediterranean recorded an ultra‑energetic particle that current models struggle to ...

A team of physicists at the SLAC National Accelerator Laboratory, in Menlo Park, California, generated the highest-current, highest-peak-power electron beams ever produced. The team has published ...

What is meant, when an experiment anticipates less than a quarter of an event, and four are registered by the detector? That number discrepancy lies at the heart of a new conundrum of kaons: ...

Physicists discovered strange supersolids, constructed new kinds of superconductors, and continued to make the case that the cosmos is far weirder than anyone suspected. Will 2024 be remembered as a ...

The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of ...

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 ...
