    • K- K′ scattering can be neglected for the long-range Coulomb interaction. Assuming that the interaction does not discriminate among sublattices at long wavelengths, the last term in Eq. is diagonal in isospin space and we can map wave functions between the K points. The spectrum is then independent of how particles are distributed over the two K points.
