Current statistics of FQHE quasiparticles in antidots

Current statistics of an antidot in the fractional quantum Hall regime is studied for Laughlin's series. The chiral Luttinger liquid picture of edge states with a renormalized interaction exponent g is adopted. Universal sub-poissonian transport regimes are identified through an analysis of current cumulants in the sequential tunneling regime. A comparison between noise and skewness is proposed in order to clearly distinguish the charge of the carriers, regardless of possible non-universal interaction renormalizations. Super-poissonian statistics is obtained in the shot limit for g < 1, and plasmonic effects due to the finite-size antidot are tracked.
