| Abstract : | We study the effect of Coulomb correlation on the transmission properties of a one-dimensional chain connected to two perfect leads in the presence of a static magnetic field. Due to the presence of a strong on-site nonlinear interaction between two opposite spins within the chain, the zero-voltage conductance exhibits strong correlations between parallel and antiparallel spin conduction channels which results in a substantial spin polarization for small chain sizes., |
