Dear QE masters, I have questions about the tag "lsigma(i)" in the bands.x run. Please help. My question is : my previous calculations are noncollinear+soc, which use spinor wavefunctions. Then I use bands.x to generate bandstructure data. However, in the previous runs, I used constrained_magnetization='total direction' and other keywords to keep all the magnetization of ions along the y axis, not z axis. Then if I want to get the major or minor spin states for each band and each k point, which one I should use: " lsigma(2)=.true." or " lsigma(3)=.true." ? Please let me know what is the actual spin quantization direction in my case here, since I kept all magnetization along y.
Best, Hong
