In this case the full wavefunction is analytically known and we thus can calculate the complete Hamiltonian. This example does not really use DFT, but shows how to calculate radial integrals from known wavefunctions.connection_to_dft index text/html 2025-11-20T02:29:43+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.quanty.org/documentation/tutorials/connection_to_dft/start?rev=1763605783&do=diff Connection to DFT and radial integrals The previous tutorials assumed that the Hamiltonian in second quantization was known. These examples show how one can obtain a tight-binding Hamiltonian and the Slater integrals defining the Coulomb interaction from density functional theory and Hartree-Fock codes.connection_to_dft index
