The interference effects in the sliding charge density wave

The dynamics of charge density wave in the external dc-ac electric field is analysed within the Gor'kov's model. The interference effects, manifested as finite steps in voltage vs dc field, are present at all rational ratios of the external ac frequency and the intrinsic frequency of the coherent oscillations, in agreement with the expeimental results. It is also shown that the beats in the voltage are to be expected in the vicinity of resonances.
