摘要：
We present a fully non-equilibrium calculation of transport properties of a quantum dot in the Kondo regime when an AC potential is applied to the gate voltage. The AC signal induces decoherence in the Kondo state. As a consequence, the obtained linear conductance and time-averaged density of states of the quantum dot evolve in a non-trivial way as a function of the frequency and intensity of the harmonic modulation, (C) 2002 Elsevier Science B.V.
