NTEP: Chapter 7. Classical Nonlinear Electron Theories and Their Connection with Qed
In this chapter of nonlinear theory of elementary particles (NTEP) a review of the nonlinear field theories in the framework of classical electrodynamics is presented. It is shown that the resultsExpand
Renormalization of Dirac ’ s Polarized Vacuum Mathieu Lewin
We review recent results on a mean-field model for relativistic electrons in atoms and molecules, which allows to describe at the same time the self-consistent behavior of the polarized Dirac sea. WeExpand
The current density in quantum electrodynamics in time-dependent external potentials and the Schwinger effect
In the framework of quantum electrodynamics (QED) in external potentials, we introduce a method to compute the time-dependence of the expectation value of the current density for time-dependentExpand
From Heisenberg–Euler Lagrangian to the discovery of Chromomagnetic Gluon Condensation
I reexamine the phenomena of the chromomagnetic gluon condensation in Yang–Mills theory. The extension of the Heisenberg–Euler Lagrangian to the Yang–Mills theory allows to calculate the effectiveExpand
Perturbative description of the fermionic projector: normalization, causality and Furry's theorem
The causal perturbation expansion of the fermionic projector is performed with a contour integral method. Different normalization conditions are analyzed. It is shown that the correspondingExpand
The current density in quantum electrodynamics in external potentials
We review different definitions of the current density for quantized fermions in the presence of an external electromagnetic field. Several deficiencies in the popular prescription due to SchwingerExpand
Existence of Atoms and Molecules in the Mean-Field Approximation of No-Photon Quantum Electrodynamics
The Bogoliubov–Dirac–Fock (BDF) model is the mean-field approximation of no-photon quantum electrodynamics. The present paper is devoted to the study of the minimization of the BDF energy functionalExpand
Non-Perturbative Mass and Charge Renormalization in Relativistic No-Photon Quantum Electrodynamics
AbstractStarting from a formal Hamiltonian as found in the physics literature – omitting photons – we define a renormalized Hamiltonian through charge and mass renormalization. We show that theExpand
Electron Positron Pair Production in Strong Electric Fields
This work covers electron positron pair production in spatially homogeneous electric (and magnetic) fields. Different field configurations are looked at in order to study various phenomena includingExpand
Unique continuation for many-body Schr\"odinger operators and the Hohenberg-Kohn theorem. II. The Pauli Hamiltonian
We prove the strong unique continuation property for many-body Pauli operators with external potentials, interaction potentials and magnetic fields in $L^p_{\rm loc}(\mathbb{R}^d)$, and with magneticExpand
