Isabelle Catto, Claude Le Bris and Pierre-Louis Lions On the thermodynamic limit for Hartree-Fock type models (657K, Postcript) ABSTRACT. We continue here our study of the thermodynamic limit for various models of Quantum Chemistry, this time focusing on the Hartree-Fock type models. For the reduced Hartree-Fock model, we prove the existence of the thermodynamic limit for the ground-state energy per unit volume. We also suggest a periodic problem associated to the Hartree-Fock model, and prove that it is well-posed.
