| Abstract: | The cooperative effects induced by external random dichotomic and d.c. driving are studied for charge drift and diffusion in a one-dimensional dissipative tight-binding model. For a strongly correlated dichotomic field the effect of large diffusion acceleration is demonstrated. Additionally, it is shown that the averaged current direction can be inverted by applying a strongly correlated electric field (noise-induced negative conductivity). |
