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 ...

Nonlocal stochastic quantization of scalar electrodynamics

International Journal of Theoretical Physics, 1990
Quantization of the electromagnetic interactions of scalar charged particles is considered within the stochastic Langevin and Schwinger-Dyson equations with nonlocal white noise. Fulfillment of the gauge-invariant condition in such a scheme is studied in detail.

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.

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.

The spin of the electron according to stochastic electrodynamics

Foundations of Physics, 1982
By making use of the method of moments we study some aspects of the statistical behavior of the nonrelativistic harmonic oscillator according to stochastic electrodynamics. We show that the random rotations induced on the particle by the zero-point field account for the magnitude of the spin of the electron, the result differing from the correct one(3 ...

Solution of BVPs in electrodynamics by stochastic methods

2007 IEEE Applied Electromagnetics Conference (AEMC), 2007
Field computation by the stochastic differential equation (SDE) method is demonstrated for electrostatic and electrodynamic propagation problems by considering simple examples. The solution to the inhomogeneous Helmholtz equation is first related to that a Schrodinger type of equation (parabolic in nature) by means of Laplace transformation.

The Kepler Problem In Stochastic Electrodynamics

1980
Stochastic electrodynamics is the Brownian motion of a charged particle in a random electromagnetic field with spectrum proportional to kω3 coth(kω/2kT). If the deterministic force field is simple harmonic, the properties of the system resemble closely those of the quantum-mechanical oscillator, but the extension to non-linear systems has proved to be ...

The quartic anharmonic oscillator in stochastic electrodynamics

Journal of Mathematical Physics, 1982
The case of a slightly anharmonic oscillator (with a βx4 perturbing potential) is examined in the framework of stochastic electrodynamics (SED) in full detail. We obtain the stationary probability density and the mean energy, which differs from the quantum result at order β2.

Stochastic Electrodynamics and the Bell Inequalities

1985
The basic ideas of stochastic electrodynamics are presented. In the light of these ideas, some general differences between quantum mechanics and local realistic theories are pointed out. The atomic-cascade experimental tests of Bell’s inequalities are analyzed and a loophole is reported in the refutation of local realism due to an incorrect ...

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 ...
