Rashba spin-orbit coupling
Opis:: We consider the effect of the Rashba spin-orbital coupling in two-dimensional GaAs semiconductor heavily doped with Mn, on the spin polarization of holes. Due to the strong internal spin-orbit interaction in GaAs, the spin of a hole is not a good quantum number but the hole in some energy state has a certain mean value of spin, which can be strongly affected by the Rashba spin-orbital interaction related to the substrate for 2D material.

Opis:: Theoretical analysis of the electron excitations in graphene on substrate by twisted, linear and circular polarization light is presented. We use a model of graphene with constant Rashba spin-orbit interaction. In this case, the band structure of electrons includes four energy bands. The main objective of this work is to compare light absorptions in graphene for different kinds of light, namely, twisted (with nonzero orbital angular momentum) and linear polarized light. The orbital angular momentum light is characterized by some parameters q and l, which can modify the response, while for the linear polarization, the absorption is modified only in the region determined by the Rashba spin-orbit coupling α.

Opis:: Spin Hall effect in a two-dimensional electron gas with the Rashba spin-orbit interaction is analyzed theoretically. We use the Keldysh technique for nonequilibrium processes, modified in order to take into account well-defined splitting of the Fermi surface due to strong spin-orbit coupling. Using such an approach, we reconsider the two-dimensional electron gas with the Rashba spin-orbit interaction and show that impurity scattering processes suppress the spin Hall effect.
