Rigorous justification of the Dirac–Fock model from Mittleman's definition of QED
In this talk, we study the relationship between Dirac-Fock energy and electron-positron Hartree-Fock energy. We prove the longstanding conjecture due to Mittleman: the Dirac-Fock model is an approximation of QED when the fine structure constant α is small and the velocity of light c is large. We also prove some properties about Dirac-Fock model. In addition, we will talk about some perspectives on the Dirac many-body problem.
