Microscopic modeling of ballistic transport in gated structures

We have recently launched a project whose goal is to understand in detail magnetotransport measurements on gated 2-dimensional electron systems. The motivation is twofold: first, standard interpretation of experiments, based on simple semiclassical electron trajectory concepts, has led to a number of apparent contradictions, and, second, numerical techniques have been refined so as to be able to treat realistic sample geometries. A significant step, achieved by our Russian collaboration partners, has been the reduction of computational labor so that supercomputing is no longer necessary. We expect to apply these techniques to the analysis of several recent experiments, and can offer exciting projects and theses topics to students.
