The multi-mode conductance formula for a closed ring Academic Article uri icon


  • Abstract The multi-mode conductance of a closed ring is found within the framework of a scattering approach. The expression can be regarded as a generalization of the Landauer formula. The treatment is essentially classical because we assume short coherence time. Our starting point is the Kubo formalism, but we also use a master equation approach for the derivation. As an example we calculate the conductance of a multi-mode waveguide with an attached cavity.
