    "abstract": "The influence of an external electric field on the current in charged systems\nis investigated. The results from the classical hierarchy of density matrices\nare compared with the results from the quantum kinetic theory. The kinetic\ntheory yields a systematic treatment of the nonlinear current beyond linear\nresponse. To this end the dynamically screened and field-dependent\nLenard-Balescu equation is integrated analytically and the nonlinear relaxation\nfield is calculated. The classical linear response result known as Debye -\nOnsager relaxation effect is only obtained if asymmetric screening is assumed.\nConsidering the kinetic equation of one specie the other species have to be\nscreened dynamically while the screening with the same specie itself has to be\nperformed statically. Different other approximations are discussed and\ncompared.",
