WebSince nonsymmorphic groups are actually more numerous than symmorphic groups and crystals with these symmetries occur extensively in nature (for example, the diamond lattice), these results may have widespread applicability. While Ref. [6] only applies to systems without spin-orbit coupling, our work accounts for these as well.

WebMar 5, 2014 · Dear Muthu V, At least the cut-off energy is much too low. You might need more k points to converge. By the way, cour 'conv_thr' is very strict, you probably need many iterations to converge (if ever, at least with such a low value of cut-off energy there is plenty of noise).
