Spin polarisation means that the electron density is allowed to be different
for spin up and spin down electrons. This is to account for spin configurations
with Sz .ne. 0, and for spin-symmetry broken situations. The spin-orbit
interaction is an extra term in the electronic Hamiltonian that comes from
the perturbative expansion of the relativistic energy, and thus only important
for high-speed electrons (core electrons in heavy atoms). As you can
see these are completely different concepts, irrespective of how siesta treats them,
and thus possibly not for this list?

Hi,
So does SIESTA support spin-orbit interaction calculations?
I saw in very old messages in the list that it doesn't. That ATOM generates spin dependent potentials but SIESTA neglects them. More recent messages left unanswered, someone even told that he found solution but never mentioned which one.

Is 'SpinPolarized   True' related to spin-orbit interactions????
