The Effects of Disorder on the $\nu=1$ Quantum Hall State

Mesoscale and Nanoscale Physics 2009-11-07 v1

Abstract

A disorder-averaged Hartree-Fock treatment is used to compute the density of single particle states for quantum Hall systems at filling factor ν=1\nu=1. It is found that transport and spin polarization experiments can be simultaneously explained by a model of mostly short-range effective disorder. The slope of the transport gap (due to quasiparticles) in parallel field emerges as a result of the interplay between disorder-induced broadening and exchange, and has implications for skyrmion localization.
