“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 ...

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 ...

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 ...

UNIVERSITY PARK, Pa. — 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 ...

Known as semi-Dirac fermions, particles with this bizarre behavior were first predicted 16 years ago. The discovery was made in a semi-metal material called ZrSiS, made up of zirconium, silicon and ...
