In 1956, theoretical physicist David Pines predicted that electrons in a solid can do something strange. While they normally have a mass and an electric charge, Pines asserted that they can combine to ...

Bizarre particle gains or loses mass depending on direction it travels By Michael Irving December 11, 2024 Scientists have accidentally discovered a strange particle that has mass when it moves in one ...

Here’s what you’ll learn when you read this story: In 1956, physicist David Pines theorized the existence of a massless, neutral plasmon called a “demon” that could help explain the superconductivity ...

The discovery of the Higgs boson filled in a missing piece of the standard model of particle physics, which describes matter and its interactions. A decade later, physicists continue to probe the ...

The fact that particles have mass is something most people take for granted. But what actually gives particles mass? Professor of Physics Gerry Guralnik thinks he knows the answer, but researchers are ...

For 16 years, scientists hypothesized the existence of a quasi-particle called a semi-Dirac fermion, named after mathematician Paul Dirac whose eponymous equation describes these fermions. Now, a new ...

Forget about turtles; for all practical purposes, it’s really particles all the way down. Consider the seemingly simple matter of their size, the very thing that makes them so alien. We’re typically ...
