英文摘要	Two-dimensional systems can host exotic particles called anyons whose quantum statistics are neither bosonic nor fermionic. For example, the elementary excitations of the fractional quantum Hall effect at filling factor n = 1/m (where m is an odd integer) have been predicted to obey Abelian fractional statistics, with a phase f associated with the exchange of two particles equal to p/m. However, despite numerous experimental attempts, clear signatures of fractional statistics have remained elusive. We experimentally demonstrate Abelian fractional statistics at filling factor n = 1/3 by measuring the current correlations resulting from the collision between anyons at a beamsplitter. By analyzing their dependence on the anyon current impinging on the splitter and comparing with recent theoretical models, we extract f = p/3, in agreement with predictions. © 2020 The Authors.
