Gaussian quantum fields and stochastic electrodynamics

Physical Review A, 1988
The relation between quantum electrodynamics and (classical) stochastic electrodynamics is elucidated by means of a general construction which associates with every Gaussian quantum field (for example, vacuum-free fields or coherent states at zero or nonzero temperature) a classical random field, which in the case of quantum electrodynamics yields ...

The extended charge in stochastic electrodynamics

Il Nuovo Cimento B Series 11, 1985
We derive a covariant equation for the motion of the extended charge and show how a consistent description is achieved for nonrelativistic velocities. If the external force is generated by the classical stochastic zero-point electromagnetic field, the equation of motion has the form of a Langevin equation with memory.

The harmonic oscillator in stochastic electrodynamics

Il Nuovo Cimento B Series 11, 1974
Classical electrodynamics with the hypothesis of a universal, Lorentz invariant, background radiation (stochastic electrodynamics) has been proposed as a possible alternative to quantum electrodynamics. The stochastic equations of motion of a charged particle are derived according to this theory, and they are compared with those of Brownian motion.

Stochastic Electrodynamics an Overview

1983
As a sequel to the absorber theory of radiation of Wheeler and Feynman,1 Braffort and Tzara2 postulated the existence of a universal random electromagnetic field at the absolute zero of temperature—the zero-point field.

Stochastic electrodynamics as a foundation for quantum mechanics

Physics Letters A, 1976
Abstract We develop a statistical description for a particle coupled to the zero-point radiation field, and apply it to the harmonic oscillator. We recover the quantum mechanical description as a limiting case of the corresponding statistical description in configuration space.

Spontaneous emission and stochastic electrodynamics

Lettere al Nuovo Cimento, 1984
Einstein's spontaneous emission is considered as the emission induced by the zero point field of stochastic electrodynamics. Using this concept the transition probability per unit time is calculated.

Stochastic electrodynamics. I. On the stochastic zero-point field

Foundations of Physics, 1983
This is the first in a series of papers that present a new classical statistical treatment of the system of a charged harmonic oscillator (HO) immersed in an omnipresent stochastic zero-point (ZP) electromagnetic radiation field. This paper establishes the Gaussian statistical properties of this ZP field using Bourret's postulate that all statistical ...

Quantum Theory and Linear Stochastic Electrodynamics

Foundations of Physics, 2001
We discuss the main results of Linear Stochastic Electrodynamics, starting from a reformulation of its basic assumptions. This theory shares with Stochastic Electrodynamics the core assumption that quantization comes about from the permanent interaction between matter and the vacuum radiation field, but it departs from it when it comes to considering ...

A Brief Survey of Stochastic Electrodynamics

1980
Stochastic electrodynamics and random electrodynamics are the names given to a particular version of classical electrodynamics. This purely classical theory is Lorentz’s classical electron theory(1) into which one introduces random electromagnetic radiation (classical zero-point radiation) as the boundary condition giving the homogeneous solution of ...
