Quantum-Classical Correspondence in Nonrelativistic Electrodynamics [PDF]

, 1999
A form of classical electrodynamic field exists which gives exact agreement with the operator field of quantum electrodynamics (QED) for the Lamb shift of a harmonically bound point electron. Here it is pointed out that this form of classical theory with

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 ...

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.

Quantum theory of an electromagnetic observer: Classically behaving macroscopic systems and the emergence of the classical world in quantum electrodynamics

, 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

The Electromagnetic Three-Body Problem With Radiation Terms Existence-Uniqueness of Periodic Orbit (II)

Results in Nonlinear Analysis, 2020
The primary goal of the present paper is to prove an existence-uniqueness of periodic solution of the equations of motion for the 3-body problem of classical electrodynamics.

Instantaneous fields in classical electrodynamics

, 2004
In this paper we express the retarded fields of Maxwell's theory in terms of the instantaneous fields of a Galilei-invariant electromagnetic and we find the vector function ${\boldsymbol{\chi}}_{\ab{L}}$ whose spatial and temporal derivatives transform ...

Maxwell\u27s Paradox: Classical Electrodynamics and its Time Reversal Invariance [PDF]

, 2015
In this paper, I argue that the recent discussion on the time - reversal invariance of classical electrodynamics (see (Albert 2000: ch.1), (Arntzenius 2004), (Earman 2002), (Malament 2004),(Horwich 1987: ch.3)) can be best understood assuming that the ...

Hydrogen Atom as a Nonlinear Oscillator Under Circularly Polarized Light: Epicyclical Electron Orbits

Hydrogen
We used Clifford algebra Cl2,0 to find the 2D orbit of a hydrogen electron under a Coulomb force and a perturbing circularly polarized electric field of light at angular frequency ω, which is turned on at time t=0 via a unit step switch.

Integrated Fabry–Perot Cavities: A Quantum Leap in Technology

Encyclopedia
Integrated Fabry–Perot cavities (IFPCs), often referred to as nanobeams due to their form factor and size, have profoundly modified the landscape of integrated photonics as a new building block for classical and quantum engineering.

Locality, QED and classical electrodynamics

Annalen der Physik, 1998
Abstract We report on some conceptual changes in our present understanding of Quantum Field Theory and muse about possible consequences for the understanding of v > c signals.
