Direct observation of anyonic braiding statistics

J Nakamura, S Liang, GC Gardner, MJ Manfra - Nature Physics, 2020 - nature.com
Anyons are quasiparticles that, unlike fermions and bosons, show fractional statistics when
two of them are exchanged. Here, we report the experimental observation of anyonic …

Impact of bulk-edge coupling on observation of anyonic braiding statistics in quantum Hall interferometers

J Nakamura, S Liang, GC Gardner… - Nature Communications, 2022 - nature.com
Quantum Hall interferometers have been used to probe fractional charge and statistics of
quasiparticles. We present measurements of a small Fabry–Perot interferometer in which the …
