  We study transport properties of a strongly correlated monoatomic chain
coupled to metallic leads. Our system is described by tight binding
Hubbard-like model in the limit of strong on-site electron-electron
interactions in the wire. The equation of motion technique in the slave boson
representation has been applied to obtain analytical and numerical results.
Calculated linear conductance of the system shows oscillatory behavior as a
function of the wire length. We have also found similar oscillations of the
electron charge in the system. Moreover our results show spontaneous spin
polarization in the wire. Finally, we compare our results with those for
non-interacting chain and discuss their modifications due to the Coulomb
interactions in the system.
