Abstract
The low temperature properties of single level molecular quantum dots including both electron-electron and electron-vibration interactions, are theoretically investigated. The calculated differential conductance in the Kondo regime exhibits not only the zero bias anomaly but also side peaks located at bias voltages which coincide with multiples of the energy of vibronic mode V Ω/e. We obtain that the evolution with temperature of the two main satellite conductance peaks follows the corresponding one of the Kondo peak when Ω ≫ kBTK, TK being the Kondo temperature, in agreement with recent transport measurements in molecular junctions. However, we find that this is no longer valid when Ω is of the order of a few times kBTK.
