We have investigated the shot noise affected by the perturbation of two microwave fields (MWFs) with frequencies ω<Subscript>1</Subscript> and ω<Subscript>2</Subscript>, which can be classified as the commensurate and incommensurate external ac fields. The time-dependent current correlation function and the spectral density of shot noise...</subscript></subscript>
