Non-Relativistic Quantum Electrodynamics and the Coulomb Interaction

open access: yesPhysics
This review explores the foundations of non-relativistic quantum electrodynamics (QED) and its application to atoms and molecules. It follows the traditional route of placing classical electrodynamics in an Hamiltonian framework, followed by Dirac’s ...

Path integral quantization of generalized Stueckelberg electrodynamics: A Faddeev-Jackiw approach

open access: yesNuclear Physics B, 2023
We build a setup for path integral quantization through the Faddeev-Jackiw approach, extending it to include Grassmannian degrees of freedom, to be later implemented in a model of generalized electrodynamics that involves fourth-order derivatives in the ...

Promoting the Mathematization of Physics: Hermann Minkowski's Draft Presentations of His 1908 “Grundgleichungen” Paper

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
I present and discuss two drafts of remarks prepared by the mathematician Hermann Minkowski (1864–1909). They were composed in December 1907 while preparing his paper on the “Basic Equations of Electromagnetic Processes in Moving Bodies” for publication in the Proceedings of the Göttingen Academy of Sciences.

Discussion Note: Conceptual Problems in Classical Electrodynamics [PDF]

open access: yes, 2007
I have argued that the standard ways of modeling classical particle-field interactions rely on a set of inconsistent assumptions. This claim has been criticized in (Muller forthcoming).

Conclusions Not Yet Drawn from the Unsolved 4/3-Problem—How to Get a Stable Classical Electron

open access: yesUniverse
It has been known for over 100 years that there is a discrepancy between Maxwell’s electrodynamics and the idea of a classical electron as the “atom” of electricity.

A note on Coulomb field

open access: yesPhysics Open, 2021
Starting from Coulomb gauge scheme, we can eliminate the instant Coulomb force and replace it by propagating retarded Coulomb force field, in the realm of classical electrodynamics.

Iron Energy Carrier: Experimental Characterisation, Combustion Diagnostic and Benchmarking with Other Clean Metal Fuels

open access: yesEnergy Science &Engineering, EarlyView.
This study investigates how iron particles burn across a wide size range, revealing late‐stage nanoparticle release and a previously unrecognised shift in combustion behaviour near 118 µm. High‐speed imaging, PMT diagnostics and SEM analyses have been conducted.

The concept of vacuum in quantum electrodynamics [PDF]

open access: yes, 2010
A re-evaluation of the concept of vacuum in quantum electrodynamics is presented, focusing on the vacuum of the quantized electromagnetic field. In contrast to the ‘nothingness’ associated to the idea of classical vacuum, subtle aspects are found in ...

Supercritical Angle Fluorescence and Raman Techniques in Biophotonics

open access: yesLaser &Photonics Reviews, EarlyView.
Supercritical angle fluorescence (SAF) microscopy and supercritical angle Raman (SAR) spectroscopy have emerged as powerful tools in the field of biophotonics, enabling high‐resolution imaging and spectroscopy of biological specimens near interfaces. This review article provides a comprehensive overview of the principles, techniques, applications, and ...

Is Classical Electrodynamics an Inconsistent Theory? [PDF]

open access: yes, 2006
A critical discussion of Mathias Frisch's recent book. I discuss Frisch's argument for the inconsistency of classical electrodynamcis and the methodological morals that he draws from ...
