Query: Non linear transport in drift-diffusion equations under magnetic field   We analyze numerically and analytically the non linear transport properties
of a drift-diffusion equation in presence of a magnetic field and of a disorder
potential. For a wide range of parameters this model exhibits a plateau where
the drift velocity is almost independent on the applied electric field. This
behavior has strong similarities with the zero differential resistance states
observed experimentally in high mobility two dimensional systems. Performed
numerical simulations are in a good global agreement with the developed
analytical theory even if the later leads to overestimated negative
differential resistance values.
