WebSpin-orbit coupling can be derived by reduction of the Dirac equation to non-relativistic limit, as one of several relativistic corrections. It is then generally expressed as H s o ∝ [ p × ∇ U ( r)] ⋅ S where S = ℏ σ / 2. ( See this answer and references therein.) WebThe Rashba effect can be understood as a second order perturbation theory in which a spin-up hole, for example, jumps from a state to a with amplitude then uses the spin–orbit coupling to flip spin and go back down to the with amplitude .
