Setting Up AFQMC

Lattice Model Snippets

Each of the following snippets illustrates a somewhat isolated aspect of setting up a lattice model Hamiltonian and trial wavefunction. However, the snippets are composable and the principles demonstrated in each snippet can be applied to the cases illustrated in other snippets.

Lattice Model Setup Snippets:

• 1. Rectangular Hubbard Model
• 2. Three-Band Hubbard Model
• 3. Hubbard-Kanamori Model
• 4. Hubbard with nth-order hopping
• 5. Hubbard with Pinning Fields
• 6. Adding twist angles
• 7. Hubbard-Stratonovich Transformation Type Override
• 8. Triangular Hubbard Model
• 9. Hartree-Fock trial wavefunctions with autoHF
• 10. using an effective H for autoHF
• 11. Adding Custom Terms to the Hamiltonian
• 12. Adding Rashba SOC to the Hamiltonian
