Advanced action in classical electrodynamics

چکیده

The time evolution of a charged point particle is governed by a second-order integro-differential equation that exhibits advanced effects, in which the particle responds to an external force before the force is applied. In this paper, we give a simple argument that clarifies the origin and physical meaning of these advanced effects, and we compare ordinary electrodynamics with a toy model of electrodynamics in which advanced effects do not occur.

Simulation Results Related to Stochastic Electrodynamics

Stochastic electrodynamics (SED) is a classical theory of nature advanced signi…cantly in the 1960s by Trevor Marshall and Timothy Boyer. Since then, SED has continued to be investigated by a very small group of physicists. Early investigations seemed promising, as SED was shown to agree with quantum mechanics (QM) and quantum electrodynamics (QED) for a few linear systems. In particular, agree...

Cornelius Lanczos’s derivation of the usual action integral of classical electrodynamics

The usual action integral of classical electrodynamics is derived starting from Lanczos’s electrodynamics — a pure field theory in which charged particles are identified with singularities of the homogeneous Maxwell’s equations interpreted as a generalization of the Cauchy-Riemann regularity conditions from complex to biquaternion functions of four complex variables. It is shown that contrary t...

Stability of Uniform Rectiliner Motion of Charged Shell in Sommerfeld Model with Self-action

It is proved that in classical electrodynamics the uniform rectilinear motion of charged " rigid " sphere with self-action (Sommerfeld model) is stable. 03.50.De In classical electrodynamics long time ago in Sommerfeld works [1, see also 2] was derived the expression of self-force acting on " nonrelativistically rigid charged sphere " , i.e sphere with radius a, its center moving along trajecto...

Quantum-classical crossover in electrodynamics

A classical field theory is proposed for the electric current and the electromagnetic field interpolating between microscopic and macroscopic domains. It represents a generalization of the density functional for the dynamics of the current and the electromagnetic field in the quantum side of the crossover and reproduces standard classical electrodynamics on the other side. The effective action ...

The classical electromagnetism as used nowadays is not the theory as developed by J

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. In this way I cannot consider classical electrodynamics as reducing to quantum electrodynamics and being recovered from it by some sort of limiting...
