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

open access: yesResults 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.

Mercury's Alfvén Wing Current System Under Sub‐Alfvénic Solar Wind Conditions: Insights From Global MHD Simulations

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Mercury's proximity to the Sun results in the lowest average Alfvénic Mach number in the upstream solar wind compared to any other planet. Under extreme conditions, the upstream Alfvén speed can exceed the solar wind speed, resulting in a sub‐Alfvénic interaction in which standing Alfvén wings form.

Hot Electron‐Informed Quantum Plasmonics in Nanoparticle‐on‐Mirror Nanocavities

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
A computational model for ultrafast optical modulation of quantum phenomena at plasmonic metal interfaces is developed. Focusing on nanoparticle‐on‐mirror nanocavities, it describes temperature‐induced variations in electronic quantum behavior. This facilitates analysis of quantum plasmonics in non‐equilibrium systems, thereby expanding the realm of ...

Electron Spin or ``Classically Non-Describable Two-Valuedness'' [PDF]

open access: yes, 2007
In December 1924 Wolfgang Pauli proposed the idea of an inner degree of freedom of the electron, which he insisted should be thought of as genuinely quantum mechanical in nature.

How the Relative Contribution of DP‐1 and DP‐2 Currents Reshapes the Global Current System During Substorms

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Geomagnetic disturbances in polar regions can be decomposed into two main patterns: the Disturbance Polar (DP) 1 and 2. How their relative contribution reshapes global current system remains unclear. In this study, we classified substorms from 2010 to 2022 into weak and strong DP‐2 events based on the ratio of the eastward to westward auroral ...

A mathematical argument for the generalisation of classical electrodynamics

open access: yes, 2012
Classical electrodynamics assumes the Lorenz gauge condition. There exists a generalisation of classical electrodynamics that does not make this assumption.

Comparison between Weber's electrodynamics and classical electrodynamics [PDF]

open access: yes, 2015
We present the main aspects of Weber's electrodynamics and of Maxwell's equations. We discuss Maxwell's point of view related to Weber's electrodynamics. We compare Weber's force with Lorentz's force.

Single‐Photon Emission From TMDCs through Strong Coupling to EQ Plasmon Modes of an Au Metasurface

open access: yesNanophotonics, Volume 15, Issue 11, 13 June 2026.
Compact, deterministic solid‐state single‐photon sources that operate at room temperature and integrate with planar nanophotonics are essential for the development of scalable quantum photonic technologies. This work presents a TMDC monolayer strongly coupled to a gold (Au) metasurface featuring an electric quadrupole mode, enabling high‐purity single ...

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

open access: yesEuropean 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

open access: yesScience 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.
