The band structure of silicon, from a supercell

The KI band structure of bulk silicon. A periodic system needs localized variational orbitals, so this tutorial introduces maximally localized Wannier functions and the projections that define them, and then computes the screening parameters from total-energy differences in a supercell. It ends with the Koopmans band structure plotted against the DFT one.
