  • Tight-binding Hamiltonian via fitting of density functional theory calculations:
Textbook tight-binding Hamiltonians are created by assuming the shape of the orbitals---for instance s, p or d orbitals centered around a particular atom---and then using symmetry to calculate orbital-orbital hopping up to a particular range. In a second step the parameters associated with the degrees of freedom are determined by fitting to experimental data or first-principles calculations.

  • Tight-binding Hamiltonian via Wannierization of density functional theory calculations:
Wannierization of density functional theory (DFT) calculations starts from the diagonal Kohn-Sham Hamiltonian in the Bloch state basis and transforms into a basis of maximally localized Wannier functions (typically via Wannier90 package). The first-principles Wannier tight-binding Hamiltonian preserves the phase and the orbital information from the DFT calculations.
