Linear response of stochastic multiperiodic systems in stationary states with application to stochastic electrodynamics

The general purpose of this paper is to develop a linear response formalism for stochastic multiperiodic systems; these systems being obtained by letting some stochastic perturbation act on deterministic multiperiodic systems. Such a formalism is then applied to the absorption coefficient of the harmonic oscillator, the rigid rotator and to the hydrogen atom, these systems being treated in the framework of the Stochastic Electrodynamics (SED) theory. A computer calculation was performed in order to investigate the possible behaviour of the absorption coefficient for the case of the hydrogen atom (Coulomb potential). The results are completely at variance with respect to those of Quantum Theory, and show that SED in its present state cannot provide a reasonably general model for microphysics, even from the qualitative point of view.
