Spin Three-Body Problem of Classical Electrodynamics with Radiation Terms (I) Derivation of Spin Equations

Results in Nonlinear Analysis, 2021
In the present paper spin equations for three-body problem of classical electrodynamics are introduced. They should be considered jointly with 3-body equations of motion derived in a previous paper of the author.

Generalised non-linear electrodynamics: classical picture and effective mass generation

European Physical Journal C: Particles and Fields
Starting from a generic Lagrangian, we discuss the number of propagating degrees of freedom in the framework of generalised non-linear electrodynamics when a photon-background split is applied.

A relativistic approach to teaching electrodynamics: Deriving Maxwell's equations from first principles

Science Education Quarterly
This paper presents a novel methodology for teaching classical electrodynamics based on special relativity theory. Traditional approaches often rely heavily on empirical laws, potentially obscuring the fundamental unity of electromagnetic phenomena.

Derivation of the cut-off length from the quantum quadratic enhancement of a mass in vacuum energy constant Lambda

European Physical Journal C: Particles and Fields, 2018
Ultraviolet self-interaction energies in field theory sometimes contain meaningful physical quantities. The self-energies in such as classical electrodynamics are usually subtracted from the rest mass.

Exploring light propagation in nonlinear electrodynamics: phase and group velocities and related phenomena

European Physical Journal C: Particles and Fields
Nonlinear electrodynamics has been an important area of research for a long time. Investigations based on nonlinear Lagrangians, such as Euler–Heisenberg and Born–Infeld, are instrumental in exploring the limits of classical and quantum field theories ...

A reformulation of mechanics and electrodynamics

Heliyon, 2017
Classical mechanics, as commonly taught in engineering and science, are confined to the conventional Newtonian theory. But classical mechanics has not really changed in substance since Newton formulation, describing simultaneous rotation and translation ...

Classical Electrodynamics in Quasi-Metric Space-Time

, 2020
The quasi-metric manifold $\cal N$ is equipped with two one-parameter families of metric tensors ${\bf {\bar g}}_t$ and ${\bf g}_t$, each parametrized by the global time function $t$.

The Electromagnetic Three-Body Problem With Radiation Terms - Derivation of Equations of Motion (I)

Results in Nonlinear Analysis, 2020
The primary purpose of the present paper is to continue the previous investigations of the author and apply the technique from the two-body problem of classical electrodynamics to the three-body problem.
