    • To be more specific, consider the eigenfunction of some space-group element (R,t) fk =c fk (R is a point-group operation and t a translation vector). The action of time-reversal symmetry θ and inversion symmetry (I,0) generates new eigenfunctions with eigenvalues c and e2ikt c, respectively, as can be checked by noting that θ and (R,t) commute while (R,t) (I,0) = (E,2t) (I,0) (R,t), where E is the point-group identity. It is then evident that symmetries involving nonprimitive translations generate different phase factors for the different pseudospin triplet components at different points in the zone.

    • Notice the additional factor -1 for k points on the zone face compared to kz =0. This arises from χ [γk (dσ -1 (σz, t2) dσ)] =χ [γk (σz, - t2)] =-χ [γk (σz, t2)], i.e., the action of the translation group, e2ik t2 =-1. Here dσ = (I,0) or (2z, t2), and we used the identity (R,v) -1 (S,w) (R,v) = (R-1 SR, R-1 Sv+ R-1 w- R-1 v).
