Towards the unification of electromagnetism and gravitation via quantum-mechanical black holes (Q1576210)

The unification of electromagnetism and gravitation is realized by introducing the half spin (or double valuedness) into the geometrodynamics through the pseudospinor behavior of the negative components of the Dirac four-spinor on the scale of the Compton wavelength. It is shown that this leads to a covariant derivative and to the Kerr-Newman metric which describes the gravitational and electromagnetic field of an electron including the anomalous \(g=2\) value. It is concluded that the formalism developed in this paper resembles Weyl's original formulation, excepting that the electromagnetism does not enter as a distinct logical structure.
