Formulation of Time-Fractional Electrodynamics Based on Riemann-Silberstein Vector
Entropy, 2021 In this paper, the formulation of time-fractional (TF) electrodynamics is derived based on the Riemann-Silberstein (RS) vector. With the use of this vector and fractional-order derivatives, one can write TF Maxwell’s equations in a compact form, which ...

Magnetostatic interaction energy between a point magnet and a ring magnet
Physics Open, 2023 We find an exact closed-form expression for the magnetostatic interaction energy between a point magnet and a ring magnet in terms of complete elliptic integrals.

Journal of High Energy Physics, 2021 We give a prescription for N $$ \mathcal{N} $$ = 1 supersymmetrization of any (four-dimensional) nonlinear electrodynamics theory with a Lagrangian density satisfying a convexity condition that we relate to semi-classical unitarity.

Causality in Classical Electrodynamics [PDF]
The Physics Teacher, 2012 Causality in electrodynamics is a subject of some confusion, especially regarding the application of Faraday's law and the Ampère-Maxwell law.1–3 This has led to the suggestion that we should not teach students that electric and magnetic fields can cause each other,1 but rather focus on charges and currents as the causal agents.3 In this paper I argue ...

Frisch, Muller and Belot on an Inconsistency in Classical Electrodynamics [PDF]
, 2007 This paper follows up a debate as to whether classical electrodynamics is inconsistent. Mathias Frisch makes the claim in Inconsistency, Asymmetry and Non-Locality ([2005]), but this has been quickly countered by Fred Muller ([2007]) and Gordon Belot ...

Nuclear Gradient Expressions for Molecular Cavity Quantum Electrodynamics Simulations using Mixed Quantum-Classical Methods [PDF]
, 2022 We derive a rigorous nuclear gradient for a molecule-cavity hybrid system using the Quantum Electrodynamics Hamiltonian. We treat the electronic-photonic DOFs as the quantum subsystem, and the nuclei as the classical subsystem.

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

On “Gauge Renormalization” in Classical Electrodynamics [PDF]
Foundations of Physics, 2006 In this paper we pay attention to the inconsistency in the derivation of the symmetric electromagnetic energy-momentum tensor for a system of charged particles from its canonical form, when the homogeneous Maxwell equations are applied to the symmetrizing gauge transformation, while the non-homogeneous Maxwell equations are used to obtain the motional ...

Electromagnetic fields with vanishing quantum corrections
Physics Letters B, 2018 We show that a large class of null electromagnetic fields are immune to any modifications of Maxwell's equations in the form of arbitrary powers and derivatives of the field strength.
