    • Those pairs of triangles which are not compatible with the hexagonal symmetry should be compound in hexagons. The final result, however, is unchanged.

    • If H is the second quantization version of the Hamiltonian a projection onto the single-particle space is implied.

    • Their presence can be detected by defining A to be the majority species and comparing the number of zero A eigenstates with the sublattices imbalance.

    • note
    • For a single, doubly degenerate level a cone can only appear at the K (K ′) point. At Γ (where the relavant k group has inversion symmetry) it is easy to show by k≃p perturbation theory that degeneracy cannot be lifted at first order for parity reasons.
