Interference effect in magneto-oscillations in two-dimensional system under bichromatic irradiation

We report on the studies of magneto-oscillations caused by bichromatic irradiation in perpendicular magnetic field. Using quantum kinetic method, we have studied the case of $\omega$, $2\omega$, and the case of $\omega$, $3\omega$ frequencies. In the latter case the interference part is shown to produce a phase-sensitive contribution. Also, the final answer depends on the polarizations of the two waves.
