WebAug 28, 2024 · The HF approach seek to find the best set of orbitals that minimizes the energy of the ground state. This procedure leads to a set of optimized occupied orbitals that, in the context of solid state theory, form the valence bands, and a set of unoccupied orbitals forming the conduction band. WebThe Fock operator is a one-electron operator and solving a Hartree-Fock equation gives the energy and Hartree-Fock orbital for one electron. For a system with 2N electrons, the variable i will range from 1 to N; i.e there will be one equation for each orbital.

WebApr 10, 2024 · Hartree-Fock calculations scale quadratically with the number of k points. For molecules you only have one of those (if you see them in a Bloch theorem context at all). For solids you have many. This is, why it takes much longer. WebThe Hartree-Fock equation is an example of an integro-differential equation. These equations involve repeated calculations of integrals, in addition to the solution of a set of coupled differential equations. The Hartree-Fock equations can also be rewritten in terms of an eigenvalue problem.
