Abstract
We propose a quasiclassical model which describes kinetics of classical particles having an additional quantum degree of freedom. The later might be an electron spin in two dimensional electron gases, or sublattice index in graphene. As an application, we focus on current-induced spin accumulation in a 2DEG with spin-orbit coupling of both the Rashba and the Dresselhaus type. This phenomenon sometimes also referred to as the kinetic magnetoelectric or inverse spin-galvanic effect and shows for the system under study significant anisotropies. The approach developed here is also applied to the description of carrier transport in graphene where low energy excitations have, with respect to the sublattice degree of freedom, a similar chiral structure as the usual 2DEG with Rashba spin-orbit interaction.
