【 摘 要 】

A disorder-averaged Hartree-Fock treatment is used to compute, the density of single particle states for quantum Hall systems at filling factor 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.
