Can anyone recommend books/reviews that derives the spin-orbit coupling in second quantization. I am working on a tightbinding model and I should be able to convert the spin-orbit hamiltonian from k-space to atomic representation using Warnier states, but I can't figure out some of the aspects of deriving the hamiltonian, even though I feel I should be able to.
My derivation so far is at a stand still at the following equation
[itex] \sum_{n,n'} c_n^+c_{n'} \langle n | (E \times k) \cdot \sigma |n'\rangle[/itex]
Thank your for any help in advance.
