Why not get the exact solution instead? It depends on what you want. As you know the central assumption in one-shot perturbative GW is that the ground-state (usually Kohn-Sham [KS]) orbitals are the same as the QuasiParticle (QP) orbitals. Thus the self energy $\Sigma$ is taken to be diagonal in the...

Hello, I was among the people who developed this section, mostly to investigate issues with PAW calculations. We never did any SOC calculations, however, so we never extended it for full non-collinear magnetism, although it should work in the collinear case. To add this functionality might take some...
