A new phase of matter: Physicists achieve first demonstration of non-Abelian anyons in a quantum processor

Our physical, 3D world consists of just two types of particles: bosons, which include light and the famous Higgs boson; and fermions—the protons, neutrons, and electrons that comprise all the "stuff," present company included.

The surface knows what lies beneath: Physicists show how to detect higher-order topological insulators

Just like a book can't be judged by its cover, a material can't always be judged by its surface. But, for an elusive conjectured class of materials, physicists have now shown that the surface previously thought to be "featureless" ...
