Can someone provide guidance on how to include Spin-orbit Coupling (SoC) for the band structure calcualtion using SIESTA?

I have used the #Flag #Spin spin-orbit, but I only obtained spin dependence in one direction. Are there any other flags needed to obtain results for both up and down spins, or any alternative approaches to achieve this?

  • $\begingroup$ It is hard to know what you mean? Spin-orbit means you'll get a vector of spin, there is no "spin-up vs down", since the angles can vary in between. If you want spin-up/down to be separate spin-channels, then you would use a polarized calculation. $\endgroup$

  • $\begingroup$ using Spin-orbit explicitly means you won't have spin up/down separated in the calculations since they are interlinked. So I think you misinterpret what it really means? $\endgroup$
