Abstract: In this work we present a theoretical model to study the effect of microwaveradiation on Weiss oscillations. In our proposal Weiss oscillations, producedby an spatial periodic potential, are modulated by microwave radiation due toan interference effect between both, space and time-dependent, potentials. Thefinal magnetoresistance depends mainly on the spatial period of the spatialpotential and the frequency of radiation. Depending on the values of theseparameters, we predict that Weiss oscillations can reach zero resistancestates. On the other hand, these dissipationless transport states, created justby radiation, can be destroyed by the additional presence of a periodicspace-dependent potential. Then by tuning the spatial period or the radiationfrequency, the magnetoresistance can be strongly modified.
