Classical Electrodynamics of Point Charges [PDF]

open access: yesAnnals of Physics, 2002
A simple mathematical procedure is introduced which allows redefining in an exact way divergent integrals and limits that appear in the basic equations of classical electrodynamics with point charges. In this way all divergences are at once removed without affecting the locality and the relativistic covariance of the theory, and with no need for mass ...

Experimental verification of the Landau–Lifshitz equation

open access: yesNew Journal of Physics, 2021
The Landau–Lifshitz (LL) equation has been proposed as the classical equation to describe the dynamics of a charged particle in a strong electromagnetic field when influenced by radiation reaction.

White areas on the map of applying non-equilibrium thermodynamics: On the self accelerating electron

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2008
Classical electrodynamics displays a formula for the equation of the motion of charged particles that has run away solutions. Gyarmati's wave approach leads to a solution fitting to the classical term in the low frequency regime.

Preacceleration in classical electrodynamics

open access: yesPhysical Review E, 2002
As is well known, the Lorentz-Dirac equation follows by means of a hypothesis of simplicity. When this hypothesis is ruled out, several additional terms can be added to the one that appears in the Lorentz-Dirac equation. We study the equation that considers the two terms explicitly shown by Dirac in his paper.

Operando Tracking of Oxygen‐Vacancy Dynamics and Negative Capacitance in Ca‐Doped BiFeO3

open access: yesAdvanced Functional Materials, EarlyView.
Operando electrochemical impedance spectroscopy, combined with electrocoloration, enables a direct correlation between real‐space ionic redistribution and the corresponding frequency‐domain electrical response. In lateral Ca‐doped BiFeO3 devices, time‐resolved impedance snapshots capture the evolution from bulk‐dominated mixed conduction to an ...

The relation between classical and quantum electrodynamics [PDF]

open access: yes, 2008
In this article it is presented the idea that quantum electrodynamics presents intrinsic limitations in the description of physical processes that makes it impossible to recover from it the type of description we have with classical electrodynamics.

Unknown classical electrodynamics [PDF]

open access: yes, 2018
In this paper, we analyze some little-known inconsistencies and inaccuracies in classical electrodynamics and suggest ways to eliminate ...

Terahertz‐Nanoscale Visualization of the Microscopic Spin‐Charge Architecture of Colossal Magnetoresistive Switching

open access: yesAdvanced Science, EarlyView.
This study employs cryogenic magneto‐terahertz nanoscopy to reveal the real‐space electrodynamics of the colossal magnetoresistance transition. By capturing the terahertz electrodynamic evolution of field‐driven spin switching, the work unveils the dissipative dynamics of emergent metallic states, providing a high‐frequency view of coupled spin‐charge ...

Formulation of Electrodynamics with an External Source in the Presence of a Minimal Measurable Length

open access: yesAdvances in High Energy Physics, 2013
In a series of papers, Quesne and Tkachuk (2006) presented a D + 1-dimensional (β, β′)-two-parameter Lorentz-covariant deformed algebra which leads to a nonzero minimal measurable length.

Symmetry‐Imposed Selection Rules for Excitations of Nontrivial Plasmonic Topologies

open access: yesAdvanced Science, EarlyView.
A unified group‐theory selection rule governs the excitation of vectorial nearfield topologies across three plasmonic spin states. Derived from first principles, it predicts spin–orbit vortex splitting and multidimensional nested vortices, confirmed by phase‐resolved in situ measurements.
