Direct observation of anyonic braiding statistics at theν=1/3 fractional quantum Hall state*

Anyons are exotic quasiparticles which exhibit fractional braiding statistics. We report experimental evidence for anyonic braiding statistics at the ν = 1/3 fractional quantum Hall state in a Fabry-Perot interferometer fabricated on a GaAs/AlGaAs heterostructure. The structure incorporates screening wells to suppress Coulomb charging effects, enabling the possibility of observing the anyonic phase without confounding by bulk-edge interaction. We observe Aharonov-Bohm interference with discrete jumps in phase consistent with anyonic phase θ = 2π/3.
