Exchange-correlation enhancement of the Lande-g* factor in integer quantized Hall plateaus
arXiv:0906.0059 · doi:10.1016/j.physe.2009.11.052
Abstract
We study the emergent role of many-body effects on a two dimensional electron gas (2DEG) within the Thomas-Fermi-Poisson approximation, including both the exchange and correlation interactions in the presence of a strong perpendicular magnetic field. It is shown that, the indirect interactions widen the odd-integer incompressible strips spatially, whereas the even-integer filling factors almost remain unaffected.
