A comment on the universality of transmission distribution of a diffusive conductor — •Mihajlo Vanevic1 and Wolfgang Belzig2 — 1Department of Physics and Astronomy, University of Basel, Switzerland — 2Department of Physics, University of Konstanz, Germany
We find the distribution of transmission eigenvalues in a series of identical junctions between chaotic cavities using the circuit theory of mesoscopic transport. We show that this distribution rapidly approaches the diffusive limit as the number of junctions increases, independent of the specific scattering properties of a single junction. We obtain the cumulant generating function and the first three cumulants of the charge transfer through the system both in the normal and superconducting case.
