Abstract
Current statistics of an antidot in the fractional quantum Hall regime is studied for Laughlin's series in the chiral Luttinger liquid picture of edge states with a renormalized interaction exponent. Universal sub-poissonian transport regimes are identified at low voltages through an analysis of higher current moments. A comparison between moments is proposed in order to clearly distinguish the charge of the carriers, regardless of possible non-universal interaction renormalizations. (C) 2007 Elsevier B.V.
