Stochastic Electrodynamics: The Closest Classical Approximation to Quantum Theory

open access: yesAtoms, 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.

The Relation between Classical and Quantum Electrodynamics [PDF]

open access: yesTheoria, 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.

Causality in Classical Electrodynamics [PDF]

open access: yesPhysics 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 ...

Thermodynamic Operations and Entropy Considerations for a Ring-of-Charge Oscillator System [PDF]

open access: yesEntropy
A ring of classical charge with a charged point particle oscillating within is first analyzed. The charged particle interacts with classical electromagnetic thermal radiation, which causes the particle to fluctuate, while the ring of charge imparts a ...

Analyzing Riemann-Liouville constraints in second-order Lagrangian fractional electrodynamic models. [PDF]

open access: yesPLoS ONE
This study used second-order fractional derivatives to constrain singular Lagrangians to construct comprehensive Hamilton-Dirac equations. Notable contributions include resolving the difficulties associated with fractional derivatives.

Semi-Classical Electrodynamics and the Casimir Effect

open access: yesPhysics
From the late 1960s onwards, the groups of Barry Ninham and Adrian Parsegian, and their many collaborators, made a number of essential contributions to theory and experiment of intermolecular forces. In particular, they explored the semi-classical theory:

Formulation of Time-Fractional Electrodynamics Based on Riemann-Silberstein Vector

open access: yesEntropy, 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

open access: yesPhysics 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.

ModMax meets Susy

open access: yesJournal 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.
