N2 - We theoretically investigate an effect of electron-phonon (e-ph) interaction on transport properties in an Aharonov-Bohm (AB) ring with an embedded quantum dot. The current under finite bias is calculated using Keldysh Green function method. The e-ph interaction is taken into account by self-consistent Born approximation. We find that the amplitude of the Fano resonance diminishes and the asymmetric shape grows like a symmetric one with an increase in the bias voltage. This is in qualitative agreement with experimental results. We also study the e-ph interaction in an interferometer of double quantum dots.
