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 hig
Dirac defines an observable to be a real dynamical variable with a complete set of eigenstates. It is shown that the density operatorb= Z, 6( i$ -r), is a quantum-mechanical observable whose expectation value is the particle density and that the integral form of this operator, the number operator fi
By the method of capacitance spectroscopy and of magnetotransport we have investigated the = 1 3 and 2 3 fractionalquantum-Hall-e ect (FQHE) states in gated GaAs=AlGaAs heterojunctions with tuned electron areal density. Our experimental results conΓΏrm the theoretical prediction of the fractional qua
