Scientific paper

We summarize the main results of a microscopically based kinetic theory, applicable to open quantum point contacts (QPCs) driven up to high fields. The governing role of gauge invariance -- and the many-body sum rules for the electron gas -- lead to stringent constraints on both transport and fluctuations. These constraints exert a dominant influence on the observable properties of QPCs and similar open mesoscopic conductors. We illustrate this in the context of certain predictions within purely phenomenological models of mesoscopic transport.
