Abstract
  • 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. (literal)
