Spin dynamics of two-dimensional electrons with Rashba spin-orbit coupling and electron-electron interactions
arXiv:0801.4132 · doi:10.1103/PhysRevB.78.195325
Abstract
We study the spin dynamics of two dimensional electron gases (2DEGs) with Rashba spin-orbit coupling by taking account of electron-electron interactions. The diffusion equations for charge and spin densities are derived by making use of the path-integral approach and the quasiclassical Green's function. Analyzing the effect of the interactions, we show that the spin-relaxation time can be enhanced by the electron-electron interaction in the ballistic regime.
