Two Hartree-Fock models for the vacuum polarization [PDF]
Philippe Gravejat, Christian Hainzl, Mathieu Lewin, Eric SéréWe review recent results about the derivation and the analysis of two Hartree-Fock-type models for the polarization of vacuum. We pay particular attention to the variational construction of a self-consistent polarized vacuum, and to the physical agreement between our non-perturbative construction and the perturbative description provided by Quantum Electrodynamics.View original: http://arxiv.org/abs/1209.6338
