Exchange-enhanced spin-splitting in a two-dimensional electron gas in the presence of the Rashba spin-orbit interaction
چکیده انگلیسی
We present a theoretical study on how many-body effects can affect the spin-splitting of a two-dimensional electron gas in the presence of the Rashba spin-orbit interaction. The standard Hartree-Fock approximation and Green's function approach are employed to calculate the energy spectrum and density of states of a spin-split two-dimensional electron gas (2DEG). We find that the presence of the exchange interaction can enhance significantly the spin-splitting of a 2DEG on top of the Rashba effect. The physical reasons behind this important phenomenon are discussed.
