Bridging quantum noise and classical electrodynamics with stochastic methods. [PDF]
Nat CommunThe development of emerging technologies in quantum optics demands accurate models that faithfully capture genuine quantum effects. Mature semiclassical approaches reach their limits when confronted with quantized electromagnetic fields, while full ...

Formulation of Time-Fractional Electrodynamics Based on Riemann-Silberstein Vector
Entropy, 2021 In this paper, the formulation of time-fractional (TF) electrodynamics is derived based on the Riemann-Silberstein (RS) vector. With the use of this vector and fractional-order derivatives, one can write TF Maxwell’s equations in a compact form, which ...

Magnetostatic interaction energy between a point magnet and a ring magnet
Physics Open, 2023 We find an exact closed-form expression for the magnetostatic interaction energy between a point magnet and a ring magnet in terms of complete elliptic integrals.

Analyzing Riemann-Liouville constraints in second-order Lagrangian fractional electrodynamic models. [PDF]
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.

The Relation between Classical and Quantum Electrodynamics
Theoria, 2011 Quantum electrodynamics presents intrinsic limitations in the description of physical processes that make it impossible to recover from it the type of description we have in classical electrodynamics.

Causality in Classical Electrodynamics [PDF]
The Physics Teacher, 2012 Causality in electrodynamics is a subject of some confusion, especially regarding the application of Faraday's law and the Ampère-Maxwell law.1–3 This has led to the suggestion that we should not teach students that electric and magnetic fields can cause each other,1 but rather focus on charges and currents as the causal agents.3 In this paper I argue ...

Journal of High Energy Physics, 2021 We give a prescription for N $$ \mathcal{N} $$ = 1 supersymmetrization of any (four-dimensional) nonlinear electrodynamics theory with a Lagrangian density satisfying a convexity condition that we relate to semi-classical unitarity.

Mesoscopic electrodynamics at metal surfaces
Nanophotonics, 2021 Plasmonic phenomena in metals are commonly explored within the framework of classical electrodynamics and semiclassical models for the interactions of light with free-electron matter. The more detailed understanding of mesoscopic electrodynamics at metal

On “Gauge Renormalization” in Classical Electrodynamics [PDF]
Foundations of Physics, 2006 In this paper we pay attention to the inconsistency in the derivation of the symmetric electromagnetic energy-momentum tensor for a system of charged particles from its canonical form, when the homogeneous Maxwell equations are applied to the symmetrizing gauge transformation, while the non-homogeneous Maxwell equations are used to obtain the motional ...
