We study an electron transport through a quantum dot in the presence of time-dependent fields. The dot is described by a single level and the intra-dot Coulomb interaction is introduced within the Hartree-Fock approximation. The external fields cause a time-dependent shift of the energy spectrum of the leads and quantum dot. We take into account the spin-polarized solutions for the quantum dot charge. We calculated the time dependence of the current and charge accumulated on the dot, the average current and charge vs. the source-drain and gate voltages in dependence on the Coulomb interaction strength and the frequencies and amplitude of the external fields.
