In a study, physicists now observed a class of quantum particles called fractional excitons, which behave in unexpected ways and could significantly expand scientists' understanding of the quantum ...

Forty years ago, Frank Wilczek was mulling over a bizarre type of particle that could live only in a flat universe. Had he put pen to paper and done the calculations, Wilczek would have found that ...

Supercomputers step particles through a virtual world to give a history of their movement. The results are compared to physical experiments. High energy physicists run on a treadmill that keeps ...
