Stochastic Electrodynamics: The Closest Classical Approximation to Quantum Theory

Atoms, 2019
Stochastic electrodynamics is the classical electrodynamic theory of interacting point charges which includes random classical radiation with a Lorentz-invariant spectrum whose scale is set by Planck’s constant.

The Relation between Classical and Quantum Electrodynamics [PDF]

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.

Bridging quantum noise and classical electrodynamics with stochastic methods [PDF]

Nature Communications
The 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 ...

Thermodynamic Operations and Entropy Considerations for a Ring-of-Charge Oscillator System [PDF]

Entropy
A ring of classical charge with a charged point particle oscillating within is first analyzed. The charged particle interacts with classical electromagnetic thermal radiation, which causes the particle to fluctuate, while the ring of charge imparts a ...

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

PLoS ONE
This 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.

Energy Considerations of Classical Electromagnetic Zero-Point Radiation and a Specific Probability Calculation in Stochastic Electrodynamics

Atoms, 2019
The zero-point (ZP) radiation field in stochastic electrodynamics (SED) is considered to be formally infinite, or perhaps bounded by mechanisms yet to be revealed someday.

Semi-Classical Electrodynamics and the Casimir Effect

Physics
From the late 1960s onwards, the groups of Barry Ninham and Adrian Parsegian, and their many collaborators, made a number of essential contributions to theory and experiment of intermolecular forces. In particular, they explored the semi-classical theory:

Classical Electrodynamics [PDF]

, 1998
This text for the graduate classical electrodynamics course was left unfinished upon Julian Schwinger's death in 1994, but was completed by his coauthors, who have brilliantly recreated the excitement of Schwinger's novel approach.
