      abstract     = {The effect of Rashba spin-orbit interaction in quantum
                      wires with hard-wall boundaries is discussed. The exact
                      wavefunction and eigenvalue equation are worked out,
                      pointing out the mixing between the spin and spatial parts.
                      The spectral properties are also studied within perturbation
                      theory with respect to the strength of the spin-orbit
                      interaction and diagonalization procedure. A comparison is
                      made with the results of a simple model, the two-band model,
                      that takes account only of the first two sub-bands of the
                      wire. Finally, the transport properties within the ballistic
                      regime are analytically calculated for the two-band model
                      and through a tight-binding Green function for the entire
                      system. Single and double interfaces separating regions with
                      different strengths of spin-orbit interaction are analysed
                      by injecting carriers into the first and the second
                      sub-band. It is shown that in the case of a single interface
                      the spin polarization in the Rashba region is different from
                      zero, and in the case of two interfaces the spin
                      polarization shows oscillations due to spin-selective bound
                      states.},
