Geometrical structure of electrodynamics in 5D spacetimes as a candidate for quantum gravity — •Wolf-Dieter R. Stein — Helmholtz-Zentrum Berlin für Materialien und Energie, Berlin, Germany

Considering the Gauss-Bonnet-Chern-Theorem (GBC) for two and four dimensional space-like submanifolds of a five-dimensional spacetime a geometrically given structure of classical electrodynamics different from that discussed by Kaluza and Klein is investigated. Magnetic flux and charge quantization as a result of topology are discussed with regard to the recent finding of quantized orbital magnetic flux in atoms to be fundamental for the quantization of electrodynamics. The dynamics of the system will be discussed within canonical formalism and shows similarities to the time evolution of a quantum mechanical system. The model will be analysed in terms of being a candidate for a quantum theory of gravitation.
