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 ...

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.

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.

What Counts as a Newtonian System? The View from Norton’s Dome [PDF]

, 2010
If the force on a particle fails to satisfy a Lipschitz condition at a point, it relaxes one of the conditions necessary for a locally unique solution to the particle’s equation of motion.

The Electromagnetic Three-Body Problem With Radiation Terms Existence-Uniqueness of Periodic Orbit (II)

Results in Nonlinear Analysis, 2020
The primary goal of the present paper is to prove an existence-uniqueness of periodic solution of the equations of motion for the 3-body problem of classical electrodynamics.

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 ...

Between classical and quantum [PDF]

, 2005
The relationship between classical and quantum theory is of central importance to the philosophy of physics, and any interpretation of quantum mechanics has to clarify it.

Stability and thermodynamic topology of logarithmic nonlinear electrodynamics black holes with exponential entropy corrections

Physics Letters B
We investigate the thermodynamic stability and phase structure of black holes in logarithmic nonlinear electrodynamics (LNED) with non-perturbative exponential corrections to the Bekenstein–Hawking entropy.

Open or Closed? Dirac, Heisenberg, and the Relation between Classical and Quantum Mechanics [PDF]

, 2004
This paper describes a long-standing, though little-known, debate between Paul Dirac and Werner Heisenberg over the nature of scientific methodology, theory change, and intertheoretic relations. Following Heisenberg’s terminology, their disagreements can
