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.

Quantum electrodynamics divergencies [PDF]
Vojnotehnički Glasnik, 2021 Introduction/purpose: The problem of divergencies in Quantum Electrodynamics (QED) is discussed. Methods: The renormalisation group method is employed for dealing with infinities in QED.

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 ...

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.

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

ARO-The Scientific Journal of Koya University, 2021 Two-dimensional photonic crystal nanocavities were designed to tailor cavity quantum electrodynamics. Enhancing the spontaneous emission of low-quality factor nanocavity with embedded CdSe quantum dots (QDs) emitters is the aim of this study.

Ultimate quantum limit for amplification: a single atom in front of a mirror
New Journal of Physics, 2021 We investigate three types of amplification processes for light fields coupling to an atom near the end of a one-dimensional (1D) semi-infinite waveguide. We consider two setups where a drive creates population inversion in the bare or dressed basis of a

Quantum Hall phases emerging from atom–photon interactions
npj Quantum Information, 2021 We reveal the emergence of quantum Hall phases, topological edge states, spectral Landau levels, and Hofstadter butterfly spectra in the two-particle Hilbert space of an array of periodically spaced two-level atoms coupled to a waveguide (waveguide ...

The Relation between Classical and Quantum Electrodynamics
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.

Atomic-waveguide quantum electrodynamics
Physical Review Research, 2020 Atom arrays are a new type of quantum light-matter interface. Here we propose to employ one-dimensional ordered arrays as atomic waveguides. These arrays support optical guided modes that do not decay into free space.
