摘要

The theory of general relativity (GR) [1,2] has successfully built a relation between the geometry of spacetime and the energy-momentum tensor of matter.Einstein has extensively quested for potential unified models of electromagnetism and gravity at a classical unified field theory and spent the last two decades of his life to the search for a unified field theory.A scaling gauge symmetry [3] was proposed by Weyl for an attempt to characterize the electromagnetism.Kaluza and Klein [4,5] extended the GR to a five dimensional spacetime for trying to unify the electromagnetism.
