Numerical calculation of the Landauer conductance through an interacting   electron system in the Hartree-Fock approximation
  We develop a new numerical method to calculate the Landauer conductance through an interacting electron system in the first order perturbation or in the self-consistent Hartree-Fock approximation. It is applied to one and two dimensional systems with nearest-neighbor electron-electron interaction.
