Les potentiels non gravitationnels et la structure de l'espace-temps

Abstract

The subject of this dissertation consists in analyzing a recent proposition, advanced by C.C.Barros, in which the non gravitational interactions can affect the space-time metric as in gravity. In fact, in the context of the Schwarzschild solution, the hydrogen atom is described in a completely new way : instead of following the usual approach to describe the electron under the Coulomb potential by using the minimal coupling, the "proton-electron" interaction is rather incorporated in the metric. In this context, we reproduce in this dissertation the same equations as predicted in Dirac theory for the weak potential approximation. Contrary to the statement made by Barros, claiming that he brought an insignificant correction to the electron levels, at the end of our analysis, we assert that this new approach has the merit of reproducing the relativistic spectrum as known in the Dirac theory. These spectacular results incite us to wonder about the role of the Principle of Equivalence in the foundations of the general theory of relativity.
