Un-renormalized classical electromagnetism [PDF]
Annals of Physics, 2006 This paper follows in the tradition of direct-action versions of electromagnetism having the aim of avoiding a balance of infinities wherein a mechanical mass offsets an infinite electromagnetic mass so as to arrive at a finite observed value. Given that, in this respect the direct-action approached ultimately failed because its initial exclusion of ...

Problems in Classical Electromagnetism [PDF]
, 2017 This second edition adds 46 new problems, for a total of 203. The solutions to certain “old” problems have been revised for improved clarity, in response to questions and comments from our students (second-year students in the Master’s in Physics program).

Classical analog of electromagnetically induced transparency [PDF]
American Journal of Physics, 2002 We present a classical analog of electromagnetically induced transparency (EIT). In a system of just two coupled harmonic oscillators subject to a harmonic driving force, we reproduce the phenomenology observed in EIT. We also describe a simple experiment with two linearly coupled RLC circuits which can be incorporated into an undergraduate laboratory.

Nonlinear extensions of gravitating dyons: from NUT wormholes to Taub-Bolt instantons
Journal of High Energy Physics, 2021 Recent work has shown the existence of a unique nonlinear extension of electromagnetism which preserves conformal symmetry and allows for the freedom of duality rotations.

Complex variational calculus with mean of (min, +)-analysis
Trends in Computational and Applied Mathematics, 2018 One develops a new mathematical tool, the complex (min, +)-analysis which permits to define a new variational calculus analogous to the classical one (Euler-Lagrange and Hamilton Jacobi equations), but which is well-suited for functions defined from C^n

Classical physics from amplitudes on curved backgrounds
Journal of High Energy Physics, 2022 We generalise the Kosower-Maybee-O’Connell (KMOC) formalism relating classical observables and scattering amplitudes to curved backgrounds. We show how to compute the final semiclassical state for a particle moving in a curved background in terms of ...

Dual electromagnetism: helicity, spin, momentum and angular momentum
New Journal of Physics, 2013 The dual symmetry between electric and magnetic fields is an important intrinsic property of Maxwell equations in free space. This symmetry underlies the conservation of optical helicity and, as we show here, is closely related to the separation of spin ...

AIMS Mathematics, 2022 The approximate solution of the Kersten-Krasil'shchik coupled Korteweg-de Vries-modified Korteweg-de Vries system is obtained in this study by employing a natural decomposition method in association with the newly established Atangana-Baleanu derivative ...

The quantum vacuum at the foundations of classical electrodynamics [PDF]
, 2010 In the classical theory of electromagnetism, the permittivity and the permeability of free space are constants whose magnitudes do not seem to possess any deeper physical meaning.

Two controversies in classical electromagnetism [PDF]
SPIE Proceedings, 2006 This paper examines two controversies arising within classical electromagnetism which are relevant to the optical trapping and micromanipulation community. First is the Abraham-Minkowski controversy, a debate relating to the form of the electromagnetic energy momentum tensor in dielectric materials, with implications for the momentum of a photon in ...
