Why can't we change the spin angular momentum of electrons with an external optical field?

I have read this paper many times: Coupled Spin and Valley Physics in Monolayers of MoS2 and Other Group-VI Dichalcogenides. Interestingly, this paper is also discussed many times in this community, ...

Spin orbit coupling from spin polarized density of states?

My knowledge in these areas of physics is lacking, so please expect naivety ahead (perhaps, dumb down your answer accordingly). From what I read online, spin orbit coupling is how the angular momentum ...
