Chern numbers and adiabatic transport in networks with leads

Abstract

We study the Chern numbers associated with the adiabatic conductances of mesoscopic systems with leads. We describe the results of exact calculations of all the Chern numbers of several model networks. For a network with one lead we find the integer conductances 0,±1. For a network with three leads we find noninteger conductances bounded by 1.
