Quantum of the Third Kind: Anyons

by Dr Frank Wilczek (Stockholm University)

For many years, physicists thought that all particles fall into two kingdoms: bosons and fermions.   They were wrong.  Anyons – emergent particles that have a kind of memory – form a new kingdom.  Recently the predicted appearance of anyon behavior in the fractional quantum Hall effect was confirmed, in beautiful experiments.  Vigorous efforts are afoot to observe anyons in other states of matter, and to mass-produce for use in quantum computing.  The age of anyons is upon us.
