Scientists have made a satisfying and intriguing physics discovery some 16 years after it was first predicted to be a possibility: a quasiparticle (a group of particles behaving as one) that only has ...

For the first time, scientists have observed a collection of particles, also known as a quasiparticle, that's massless when moving one direction but has mass in the other direction. The quasiparticle, ...

“We weren’t even looking for a semi-Dirac fermion,” said Yinming Shao, a physics professor and lead author on the study. “We were seeing signatures we didn’t understand — and it turns out we had made ...

Research into quantum criticality in Dirac fermion systems has rapidly evolved over recent years, enhancing our understanding of phase transitions driven by quantum fluctuations at zero temperature.

Scientists have observed a unique particle that moves easily one way, yet resists at 90 degrees. These semi-Dirac fermions were observed using their energy signature in a topological metal. Particles ...

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 ...

One of the cleanest rules in theoretical physics may have a crack in it. A preprint posted in May 2026 by physicists Vladimir ...

Urbana, IL -- Fundamental research in condensed matter physics has driven tremendous advances in modern electronic capabilities. Transistors, optical fiber, LEDs, magnetic storage media, plasma ...

For the first time, scientists have caught a glimpse of a strange and elusive creature in the world of quantum physics—a semi-Dirac fermion. This unusual quasiparticle behaves as if it has no mass in ...

An international team of scientists has discovered an exotic new form of topological state in a large class of 3D semi-metallic crystals called Dirac semimetals. The researchers developed extensive ...
