Observation of the scaling dimension of fractional quantum Hall anyons.

ABSTRACT: Unconventional quasiparticles emerging in the fractional quantum Hall regime^1,2 present the challenge of observing their exotic properties unambiguously. Although the fractional charge of quasiparticles has been demonstrated for nearly three decades^3-5, the first convincing evidence of their anyonic quantum statistics has only recently been obtained^6,7 and, so far, the so-called scaling dimension that determines the propagation dynamics of the quasiparticles remains elusive. In particular, although the nonlinearity of the tunnelling quasiparticle current should reveal their scaling dimension, the measurements fail to match theory, arguably because this observable is not robust to non-universal complications^8-12. Here we expose the scaling dimensi
