DYNAMICAL ONSAGER COEFFICIENTS IN ONE-DIMENSIONAL BALLISTIC TRANSPORT

Within a correlation-function (CF) formalism we present a theoretical analysis of the Kelvin-Onsager coefficients (KOC) relating generalized fluxes to the applied external forces for a carrier system in a one-d imensional ballistic structure. We consider a two terminal device with length l terminated by ideal contacts and investigate the transition from equilibrium to non-equilibrium conditions. The basis of the kinet ic description are the transport equations for the Wigner function and the associated variance. The correlation functions of extensive varia bles (e.g. carrier number and energy) and the respective currents corr espond to moments of the Wigner correlation function and the Fourier t ransform of the current correlation functions yield the dynamical Kelv in-Onsager coefficients.
