Jean Dolbeault, Patricio Felmer, Mathieu Lewin Stability of the Hartree-Fock model with temperature (525K, Postscript) ABSTRACT. This paper is devoted to the Hartree-Fock model with temperature in the euclidean space. For large classes of free energy functionals, minimizers are obtained as long as the total charge of the system does not exceed a threshold which depends on the temperature. The usual Hartree-Fock model is recovered in the zero temperature limit. An orbital stability result for the Cauchy problem is deduced from the variational approach.
