Structured energy distribution and coherent ac transport in mesoscopic wires
Abstract
Electron energy distribution in a mesoscopic ac-driven diffusive wire generally is not characterized by an effective temperature. At low temperatures, the distribution has a form of a multistep staircase, with the step width equal to the field energy quantum. Analytic results for the field frequency high and low compared to Thouless energy are presented, while the intermediate-frequency regime is analyzed numerically. Manifestations in the tunneling spectroscopy and noise measurements are discussed.
