                  "Smearing of charge fluctuations in a grain 
                        by spin-flip assisted tunneling"

        Kivonat:

        "I will present new results concerning the study of the charge
        fluctuations of a grain coupled to a lead via a small quantum
        dot. Such simple device exhibits a very rich behavior. I will
        notably show that the strong entanglement of charge and spin
        flips in this setup can result in a stable SU(4) Kondo fixed
        point, which considerably smears out the Coulomb staircase
        behavior already in the weak tunneling limit. This behavior
        is robust enough to be experimentally observable."
