Braided quantum electrodynamics
Journal of High Energy Physics, 2023 The homotopy algebraic formalism of braided noncommutative field theory is used to define the explicit example of braided electrodynamics, that is, U(1) gauge theory minimally coupled to a Dirac fermion.

The Relation between Classical and Quantum Electrodynamics [PDF]
Theoria, 2011 Quantum electrodynamics presents intrinsic limitations in the description of physical processes that make it impossible to recover from it the type of description we have in classical electrodynamics.

Stochastic Electrodynamics: The Closest Classical Approximation to Quantum Theory
Atoms, 2019 Stochastic electrodynamics is the classical electrodynamic theory of interacting point charges which includes random classical radiation with a Lorentz-invariant spectrum whose scale is set by Planck’s constant.

Two-Dimensional Quantum-Link Lattice Quantum Electrodynamics at Finite Density
Physical Review X, 2020 We present an unconstrained tree-tensor-network approach to the study of lattice gauge theories in two spatial dimensions, showing how to perform numerical simulations of theories in the presence of fermionic matter and four-body magnetic terms, at zero ...

Some Classical Models of Particles and Quantum Gauge Theories
Quantum Reports, 2022 The article contains a review and new results of some mathematical models relevant to the interpretation of quantum mechanics and emulating well-known quantum gauge theories, such as scalar electrodynamics (Klein–Gordon–Maxwell electrodynamics), spinor ...

Mesoscopic electrodynamics at metal surfaces
Nanophotonics, 2021 Plasmonic phenomena in metals are commonly explored within the framework of classical electrodynamics and semiclassical models for the interactions of light with free-electron matter. The more detailed understanding of mesoscopic electrodynamics at metal

Quantum electrodynamics in finite volume and nonrelativistic effective field theories
Physics Letters B, 2016 Electromagnetic effects are increasingly being accounted for in lattice quantum chromodynamics computations. Because of their long-range nature, they lead to large finite-size effects over which it is important to gain analytical control. Nonrelativistic
