Since it deals with Spin-Orbit coupling, I was expecting a more complicated pseudopotential than the LDA-TM one,

However, the HGH pseudo-potentials have only a few lines. Am I missing anything?

What's more, for calculation of spin-orbit coupling in LDA, can I simply use LDA-TM? Or hgh is a requirement?

Many thanks!

Well when I saw the original paper and see it is analytical form then I came to realize how it works.

Still there is one thing I am confused, that in a S-O coupling calculation, is hgh potential the only choice?
