Stochastic electrodynamics for the free particle

Journal of Mathematical Physics, 1983
The theory of stochastic electrodynamics is applied to the free particle and to the particle moving in a homogeneous field, leading to a complete temperature- and time-dependent description in phase space. After a transient time, the marginal description in configuration space coincides entirely with quantum mechanics, while the phase-space description

The Pullback Mechanism in Stochastic Electrodynamics

AIP Conference Proceedings, 2007
An argument is given why the classical theory called Stochastic Electrodynamics may reproduce scattering and ionization experiments of electrons on atomic hydrogen.

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.

Recent Developments in Linear Stochastic Electrodynamics

AIP Conference Proceedings, 2006
A detailed analysis of stochastic electrodynamics (SED) as a foundation for quantum mechanics has shown that the reasons for its failure in the case of nonlinear forces are not to be ascribed to the founding principles of the theory but to the approximation methods introduced, particularly the use of the Fokker‐Planck approximation and perturbation ...

Excited states in stochastic electrodynamics

Physical Review A, 1988
We show that the set of Wigner functions associated with the excited states of the harmonic oscillator constitutes a complete set of functions over the phase space. An arbitrary probability distribution can be expanded in terms of these Wigner functions.

The physics of stochastic electrodynamics

Il Nuovo Cimento B, 1986
The problem of the electron immersed in the random zeropoint radiation field and described by the stochastic Abraham-Lorentz equation is analysed from a new point of view. First an approximate treatment of the (statistically) stationary motion of this system is performed by using a local linearization procedure applicable to nonlinear periodic problems.

Linear Stochastic Electrodynamics

1996
In the foregoing chapter it was observed that the use of a conventional perturbative approach in SED leads to unperturbed solutions obeying classical equations of motion, whereas they should be stochastic and somehow contain ‟, if they are expected to describe the quantum world; in other words, that not even the zero-order motions of the sed system in ...

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 propagator of stochastic electrodynamics

Physical Review D, 1981
The ''elementary propagator'' for the position of a free charged particle subject to the zero-point electromagnetic field with Lorentz-invariant spectral density proportional..omega../sup 3/ is obtained. The nonstationary process for the position is solved by the stationary process for the acceleration.
