Abstract
Symmetry determines forms of band structures in the vicinity of special points in the reciprocal space of one-, two- and three-dimensional materials. Tight binding model on a crystal with four sites per primitive cell that belongs to gray layer single group pbma (45.2.315 or pbma1’ in the magnetic layer groups notation) is calculated. Fortune teller states (FT) are obtained at the Brillouin zone (BZ) corners, as predicted by group theory for non-magnetic materials with negligible spin-orbit coupling. We show further that besides these FT states, another interesting band degeneracy arises as a consequence of symmetry.
