We study a two-dimensional electron gas in a long, continuous nanowire with lateral confinement, in an external magnetic field. Three different materials are considered, GaAs, InAs and InSb. We take into account Rashba and Dresselhaus spin-orbit interactions and the Coulomb interaction within the Hartree-Fock approximation. The energy spectra, charge, and spin densities, together with charge and spin currents are calculated and compared, with and without the Coulomb interaction in a variable magnetic field. We show
that the spin currents may be amplified by the Coulomb interaction.
