Anyons in Integer Quantum Hall Magnets

Abstract

Anyons---particles with fractional electron charge that exist only in two-dimensional systems---are known to occur in materials exhibiting the fractional quantum Hall effect but were not expected in those exhibiting the integer quantum Hall effect. Now, a new study shows that chiral magnets with itinerant electrons, which exhibit the integer quantum Hall effect, can in fact host anyons, thus opening a new avenue for the search for these exotic particles.
