Charge and spin in a two-dimensional electron gas: always an exciting encounter
In this talk I will give an overview of results obtained over the last few years in the theory
of the spin-charge coupling effects in a two-dimensional electron gas. In particular, in the first
part of my presentation, I will present a SU(2) formulation of the Rashba model, which allows
an elegant description of spin Hall and Edelstein effects. I will also consider the effect of spin-orbit
coupling from impurities and the specific interplay with the Rashba spin-orbit coupling.
In the second part, I will consider how the above effects are affected in the presence of phonon scattering, non-uniform Rashba spin-orbit coupling and Weak Localization corrections.
