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 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 ...

For the first time, scientists have directly observed a semi-Dirac fermion, a quasiparticle with massless behavior in one direction and mass in another. This groundbreaking discovery, made within a ...

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 ...

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 ...
