N2 - We study cotunneling in a double-junction Coulomb blockade device under the influence of time-dependent potentials. It is shown that the ac bias leads to photon-assisted cotunneling that in some cases may dominate the transport. We derive a general nonperturbative expression for the tunneling current in the presence of oscillating potentials and give a perturbative expression for the photon-assisted cotunneling current.
