Semiclassical theory of conductance and noise in open chaotic cavities

Conductance and shot noise of an open cavity with diffusive boundary scatte ring are calculated within the Boltzmann-Langevin approach. In particular, conductance contains a nonuniversal geometric contribution, originating fro m the presence of open contacts. Subsequently, universal expressions for mu lti-terminal conductance and noise, valid for all chaotic cavities, are obt ained classically, based on the fact that the distribution function in the cavity depends only on energy, and using the principle of minimal correlati ons.
