2 5 Ja n 19 99 Charge and Statistics of Quantum Hall Quasi - Particles A numerical study of mean values and fluctuations


We present Monte Carlo studies of charge expectation values and charge fluctuations for quasi-particles in the quantum Hall system. We have studied the Laughlin wave functions for quasi-hole and quasi-electron, and also Jain's definition of the quasi-electron wave function. The considered systems consist of from 50 to 200 electrons, and the filling fraction… (More)
