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 ...

Scientists have accidentally discovered a particle that has mass when traveling in one direction, but no mass while moving in a different direction. Known as semi-Dirac fermions, particles with this ...

Quasiparticles -- long-lived particle-like excitations -- are a cornerstone of quantum physics, with famous examples such as Cooper pairs in superconductivity and, recently, Dirac quasiparticles in ...

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 illustration of the calculated structure of ZrSiS near the crossing points of its structure, showing a semi-Dirac point as a black sphere on the left. Data points as purple dots support the ...
