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 ...

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 ...

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 ...

A University of Hawaiʻi at Mānoa student-led team has developed a new algorithm to help scientists determine direction in complex two-dimensional (2D) data, with potential applications ranging from ...
