【 摘 要 】

We calculate the conductance through strongly correlated T-shaped molecular or quantum dot systems under the influence ofphonons. The system is modelled by the extended Anderson–Holstein Hamiltonian. The finite-U mean-field slave boson approachis used to study many-body effects. Phonons influence both interference and correlations. Depending on the dot unperturbed energyand the strength of electron–phonon interaction, the system is occupied by a different number of electrons that effectively interactwith each other repulsively or attractively. This leads, together with the interference effects, to different spin or charge Fano–Kondoeffects.
