A bstractThe quantum Gauss Law as an interacting field equation is a prominent feature of QED with eminent impact on its algebraic and superselection structure. It forces charged particles to be accompanied by “photon clouds” that cannot be realized in the Fock space, and prevents them from having a sharp mass [7, 19]. Because it entails the possibility of “measurement of charges at a distance”, it is well-known to be in conflict with locality of charged fields in a Hilbert space [3, 17]. We…

Quantum Electrostatics, Gauss’s Law, and a Product Picture for Quantum Electrodynamics; or, the Temporal Gauge Revised
We provide a theoretical foundation for the notion of the quantum coherent state of the electrostatic field of a static external charge distribution introduced in a 1998 paper and rederive formulae…
Perturbative versus non-perturbative quantum field theory: the method of Tao, the Casimir effect and interacting Wightman theories
We dwell upon certain points concerning the meaning of quantum field theory: the problems with the perturbative approach, and the question raised by ’t Hooft of the existence of the theory in a…

Asymptotic charges, large gauge transformations and inequivalence of different gauges in external current QED
Abstract In this paper we consider external current QED in the Coulomb gauge and in axial gauges for various spatial directions of the axis. For a non-zero electric charge of the current, we…

Symplectic reduction of Yang-Mills theory with boundaries: from superselection sectors to edge modes, and back
I develop a theory of symplectic reduction that applies to bounded regions in Yang-Mills theory and electromagnetism. In this theory superselection sectors for the electric-flux play a central role.…
Renormalization in String-Localized Field Theories: A Microlocal Analysis
Using methods of microlocal analysis, we prove that the regularization of divergent amplitudes stays a pure ultraviolet problem in string-localized field theories, despite the weaker localization.…

String Chopping and Time-ordered Products of Linear String-localized Quantum Fields
TLDR
This paper shows that almost all such string configurations can be dissected into finitely many pieces which can indeed be chronologically ordered, and fixes the time-ordered products of linear field factors outside a nullset of string configurations.
