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 However,we find that this is no longer valid when is of the order of a few times kBTK .
