Construction of the self-consistent Dirac vacuum in electromagnetic fields
Seminar Room 1, Newton Institute
AbstractThis is joint work with Philippe Gravejat, Christian Hainzl and Mathieu Lewin (arxiv.org/1204.2893). Using the Pauli-Villars regularization and arguments from convex analysis, we construct the self-consistent polarized Dirac vacuum, in the presence of small external electromagnetic fields. We describe the electrons by a Hartree-Fock-type theory and the photons by a self-consistent classical magnetic potential. The resulting vacuum polarization coincides to first order with that of full Quantum Electrodynamics.
If it doesn't, something may have gone wrong with our embedded player.
We'll get it fixed as soon as possible.
