Nonlocality, Correlations, and Magnetotransport in a Spatially Modulated Two-Dimensional Electron Gas
arXiv:2006.12339 · doi:10.1103/PhysRevLett.120.146802
Abstract
It is shown that the classical commensurability phenomena in weakly modulated two-dimensional electron systems is a manifestation of the intrinsic properties of the correlation functions describing a homogeneous electron gas in a magnetic field. The theory demonstrates the importance for consideration of nonlocal response and removes the gap between classical and quantum approaches to magnetotransport in such systems.
