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 ...

In A Nutshell Scientists discovered a previously unknown form of mixing that occurs when large groups of dense particles ...

When lasers were invented in the 1960s, they opened new avenues for scientific discovery and everyday applications from scanners at the grocery store to corrective eye surgery. Conventional lasers ...
