We study the periodic Hartree-Fock model used for the description of electrons in a crystal. The existence of a minimizer was previously shown by Catto, Le Bris and Lions (Ann. Inst. H. Poincare Anal. Non Lineaire} 18 (2001), no.6, 687--760). We prove in this paper that any minimizer is necessarily a projector and that it solves a certain nonlinear equation, similarly to the atomic case. In particular we show that the Fermi level is either empty or totally filled. 

Some mathematical models in quantum chemistry and uncertainty quantification

The contributions of this thesis work are two fold. The first part deals with the study of local defects in crystalline materials. Chapter 1 gives a brief overview of the main models used in quantum

Periodic Hartree-Fock Theory

Die Hartree-Fock-Approximation (HF) ist die am haufigsten verwendete Approximationsmethode fur Viel-Fermionen-Systeme. Wir untersuchen periodische HF-Modelle, die die Elektronen in einem Kristall

A New Approach to the Modeling of Local Defects in Crystals: The Reduced Hartree-Fock Case

This article is concerned with the derivation and the mathematical study of a new mean-field model for the description of interacting electrons in crystals with local defects. We work with a reduced

There are no unfilled shells in unrestricted Hartree-Fock theory.

We prove that in an exact, unrestricted Hartree-Fock calculation each energy level of the Hartree-Fock equation is either completely filled or completely empty. The only assumption needed is that the

Generalized Hartree-Fock theory and the Hubbard model

The familiar unrestricted Hartree-Fock variational principles is generalized to include quasi-free states. As we show, these are in one-to-one correspondence with the one-particle density matrices

On the convergence of SCF algorithms for the Hartree-Fock equations

The present work is a mathematical analysis of two algorithms, namely the Roothaan and the level-shifting algorithms, commonly used in practice to solve the Hartree-Fock equations. The level-shifting

Error bound for the Hartree-Fock energy of atoms and molecules

We estimate the error of the Hartree-Fock energy of atoms and molecules in terms of the one-particle density matrix corresponding to the exact ground state. As an application we show this error to be

The Hartree-Fock theory for Coulomb systems

For neutral atoms and molecules and positive ions and radicals, we prove the existence of solutions of the Hartree-Fock equations which minimize the Hartree-Fock energy. We establish some properties

Solutions of Hartree-Fock equations for Coulomb systems

This paper deals with the existence of multiple solutions of Hartree-Fock equations for Coulomb systems and related equations such as the Thomas-Fermi-Dirac-Von Weizäcker equation.

Asymptotics of heavy atoms in high magnetic fields: I. Lowest landau band regions

The ground state energy of an atom of nuclear charge Ze in a magnetic field B is evaluated exactly to leading order as Z ∞. In this and a companion work (see [28]) we show that there are five regions

Variational principle for many-fermion systems

If ψ is a determinantal variational trial function for the N-fermion Hamiltonian, H, with one- and two-body terms, then e 0 ⩽ 〈 ψ,Hψ〉= E(K), where e 0 is the ground-state energy, K is the one-body
