Resonant spin polarization and Hall conductances in a two-dimensional electron gas

We have studied transport properties in a two-dimensional electron gas with equal Rashba and Dresselhaus spin-orbit interactions under a perpendicular magnetic field. By employing the exact solution for this system, we found resonant charge and spin Hall conductances at a certain magnetic field, where all the nearest-neighboring Landau levels cross. Near the magnetic field, there exists a resonant spin polarization, which can also induce resonant charge and spin Hall effects.
