    • The wave function is small, but finite because we consider two vacancies, one of which is located on sublattice 1 and the remaining one is on sublattice 2. If we considered a single vacancy, the wave function would exactly vanish on the same sublattice point as the one where the vacancy is. See also the Appendix.

    • As shown in the Appendix, a vacancy on sublattice 1 and a vacancy on sublattice 2 are actually not independent. When the concentration is small, however, the effect of interference is small.
