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.

Quantum electrodynamical metamaterials [PDF]
Physical Review A, 2023 Recent experiments have revealed ultrastrong coupling between light and matter as a promising avenue for modifying material properties, such as electrical transport, chemical reaction rates, and even superconductivity. Here, we explore (ultra)strong coupling as a means for manipulating the optical response of metamaterials based on ensembles of ...

Variational Quantum Electrodynamics [PDF]
Physical Review D, 2014 A variational method is discussed, based on the principle of minimal variance. The method seems to be suited for gauge interacting fermions, and the simple case of quantum electrodynamics is discussed in detail. The issue of renormalization is addressed,

Circuit quantum electrodynamics [PDF]
Reviews of Modern Physics, 2021 Quantum mechanical effects at the macroscopic level were first explored in Josephson junction-based superconducting circuits in the 1980's. In the last twenty years, the emergence of quantum information science has intensified research toward using these circuits as qubits in quantum information processors.

Pseudo-Quantum Electrodynamics: 30 Years of Reduced QED [PDF]
EntropyCharged quasiparticles, which are constrained to move on a plane, interact by means of electromagnetic (EM) fields which are not subject to this constraint, living, thus, in three-dimensional space.

Non-Equilibrium Quantum Electrodynamics [PDF]
Physical Review D, 1997 We employ the influence functional technique to trace out the photonic contribution from full quantum electrodynamics. The reduced density matrix propagator for the spinor field is then constructed.

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

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.

Resolution of superluminal signalling in non-perturbative cavity quantum electrodynamics [PDF]
Nature Communications, 2018 Quantum Rabi model is a standard tool for describing cavity quantum electrodynamics, but the potential shortcomings of its single-mode version are usually neglected.

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.
