Exchange-enhanced spin splitting in a two-dimensional electron gas in the presence of spin-orbit interaction and magnetic fields

Journal Article


Abstract


  • Using a Greens function approach on the basis of the random-phase approximation, we examine how the many-body effect such as

    exchange interaction affects the spin-splitting in a two-dimensional electron gas system in the presence of the Rashba spinorbit

    interaction and Zeeman splitting and of quantizing magnetic fields. We show that such a many-body interaction can lower the energy

    levels of the system and enlarge the spin-splitting around the Fermi level. We also find that the exchange-enhanced spin-splitting is

    mainly achieved via intra-Landau level scattering.
