Weak localization, spin relaxation, and spin diffusion: Crossover between weak and strong Rashba coupling limits
Weak localization, spin relaxation, and spin diffusion: Crossover between weak and strong Rashba coupling limits
Disorder scattering and spin-orbit coupling are together responsible for the diffusion and relaxation of spin density in time-reversal invariant systems. We study spin relaxation and diffusion in a two-dimensional electron gas with Rashba spin-orbit coupling and spin-independent disorder, focusing on the role of Rashba spin-orbit coupling in transport. Spin-orbit coupling …
