    • Although the dropped terms in H2 are smaller than the retained terms, the justification for neglecting them is primarily the way they enter the calculation.

    • One could retain these terms in H0. It improves, slightly, the bands as a function of k vecpara.

    • For any periodic system described by a Hermitian Hamiltonian, if Q is a wave vector at a given energy, Qstar must also be a wave vector at this energy. A superlattice can be described by a Hermitian Hamiltonian and thus must have this property. Therefore, is important to show that our description of the superlattice, which is not directly based on a superlattice Hamiltonian, correctly describes this feature of the superlattice electronic structure.
