Andreev reflection eigenvalue density in mesoscopic conductors

Mesoscale and Nanoscale Physics 2009-11-10 v1 Superconductivity

Abstract

The energy-dependent Andreev reflection eigenvalues determine the transport properties of normal-superconducting systems. We evaluate the eigenvalue density to get an insight into formation of resonant electron-hole transport channels. The circuit-theory-like method developed can be applied to any generic mesoscopic conductor or combinations thereof. We present the results for experimentally relevant cases of a diffusive wire and a double tunnel junction.
