Abstract

We theoretically study the nonequilibrium transport properties in an Aharonov-Bohm ring with an embedded quantum dot, in the presence of electron-phonon interaction. The differential conductance is calculated under finite bias voltages, using Keldysh Green function method. By the perturbation of the electron-phonon interaction, we find that the Fano resonance is more suppressed with increasing bias voltage. This bias-voltage dependence of the dephasing effect cannot be obtained using the canonical transformation method of electron-phonon interaction.
