In two spatial dimensions quantum mechanical particles are not limited to being bosons or fermions as they are in three dimensions, but can be particles known as anyons. Such anyons come in two major varieties – Abelian and non-Abelian – both of which were long ago predicted to be realized in certain Fractional Quantum Hall (FQH) systems. However, experimental demonstration of anyonic braiding properties has remained elusive and very controversial. In this talk I report on recent study of Abelian and non-Abelian statistics through Fabry-Perot interferometry. New results (see arXiv:1112.3400) suggest strong evidence of both abelian and nonabelian anyons.

This talk is part of the Theory of Condensed Matter series.
