Spurious Modes in Dirac Calculations and How to Avoid Them
Mathieu Lewin,Eric Séré +1 more
TL;DR: The problem of the occurrence of spurious modes when computing the eigenvalues of Dirac operators, with the motivation to describe relativistic electrons in an atom or a molecule is considered.
Book ChapterDOI
The Microscopic Origin of the Macroscopic Dielectric Permittivity of Crystals: A Mathematical Viewpoint
TL;DR: In this article, a mathematical analysis of the Adler-Wiser formula relating the macroscopic relative permittivity tensor to the microscopic structure of the crystal at the atomic level is presented.
Proceedings ArticleDOI
The Thermodynamic Limit of Quantum Coulomb Systems: A New Approach
TL;DR: In this article, the thermodynamic limit of quantum Coulomb systems has been shown for many different models, and a general method allowing to show the existence of the limit for different models has been proposed.
Journal ArticleDOI
Properties of the periodic Hartree-Fock minimizer
Marco Ghimenti,Mathieu Lewin +1 more
TL;DR: In this paper, it was shown that any minimizer is necessarily a projector and that it solves a certain nonlinear equation, similarly to the atomic case, and that the Fermi level is either empty or totally filled.

The semi-classical limit of large fermionic systems
TL;DR: In this paper, the convergence to the Thomas-Fermi minimizers in the limit $N\to\infty was proved for a large class of interaction potentials and of external electromagnetic fields.
