Title:
Evidence for anyonic statistics in the fractional quantum Hall regime through Fabry-Perot interferometry
Speaker:
Abstract:
Fractional quantum Hall states have been predicted to host exotic quasiparticles which carry fractional charge and obey anyonic braiding statistics. Fabry-Perot interferometers have been proposed as a tool for observing these fractional properties. We have fabricated interferometers in which the bulk-edge coupling is suppressed by screening layers. At the ν= 1/3 state we observe Aharonov-Bohm interference interrupted by discrete jumps in phase, which provides experimental evidence for anyonic braiding statistics.
