Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract This study investigates the roles of neutral winds, composition and atmospheric waves in storm‐time post‐midnight equatorial plasma bubble (EPB) development using the coupled SAMI3‐WACCMX model. Simulations reveal the formation of post‐midnight EPBs extending beyond 1,500 km in altitude and persisting into the post‐sunrise period.

Analyzing Riemann-Liouville constraints in second-order Lagrangian fractional electrodynamic models.
PLoS ONEThis study used second-order fractional derivatives to constrain singular Lagrangians to construct comprehensive Hamilton-Dirac equations. Notable contributions include resolving the difficulties associated with fractional derivatives.

Generalised non-linear electrodynamics: classical picture and effective mass generation
European Physical Journal C: Particles and FieldsStarting 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.

Science Education QuarterlyThis 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.

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.

PLASMA-LIKE VACUUM IN PODOLSKY REGULARIZED CLASSICAL ELECTRODYNAMICS
, 2011 We analyze wave propagation in the vacuum of Podolsky regularized electrodynamics. Two kinds of waves were found in the theory: the traditional non-dispersive waves of Maxwell electrodynamics, and a dispersive wave reminiscent of wave propagation in a ...

European Physical Journal C: Particles and FieldsNonlinear 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 ...

On stability of renormalized classical electrodynamics
, 2003 It is shown that the total energy of the static "field + particle" system, defined in the framework of classical, renormalized electrodynamics of particles and fields, depends in an unstable way upon the field boundary data. It is argued that this phenomenon may be also an origin of the unstable dynamical behaviour of the system (i.e.

The renormalization of charge and temporality in quantum electrodynamics [PDF]
, 2008 In this article it is intended a closer look at the renormalization procedure used in quantum electrodynamics to cope with the divergent integrals that appear in higher-order calculations within the theory.

, 2015 Quantum electrodynamics under conditions of distinguishability of interactingmatter entities, and of controlled actions and back-actions between them, is considered. Such "mesoscopic quantum electrodynamics" is shown to share its dynamical structure with
