This paper studies how the static non-linear electromagnetic-vacuum spacetime of a point nucleus with a negative bare mass affects the self-adjointness of the general-relativistic Dirac Hamiltonian for a test electron, without and with an anomalous magnetic moment. This study interpolates between the previously studied extreme cases of a test electron in (a) the Reissner–Weyl–Nordstrom spacetime (Maxwell’s electromagnetic vacuum), which sports a very strong curvature singularity with negative…

The general relativistic hydrogen atom
The general relativistic Dirac equation is formulated in an arbitrary curved space-time using differential forms. These equations are applied to spherically symmetric systems with arbitrary charge
Naked Reissner-Nordström singularities and the anomalous magnetic moment of the electron field
We study the problem of the quantization of the massive charged Dirac field on a naked Reissner-Nordstr\"{o}m background. We show that the introduction of an anomalous magnetic moment for the

One-electron atom as a probe of space-time curvature
We consider a one-electron atom in an arbitrary curved space-time. After reviewing the generalization of the Dirac equation to curved space-time, we develop the perturbation theory of degenerate

We provide a new proof of Behncke's remarkable result that the Coulombic Dirac equation with nonzero anomalous magnetic moment is essentially selfadjoint (on Co( R3)4) for acny value of the Coulomb
Modified Field Equations with a Finite Radius of the Electron
THE attempts to combine Maxwell's equations with the quantum theory (Pauli, Heisenberg, Dirac) have not succeeded. One can see that the failure does not lie on the side of the quantum theory, but on

Non-existence of time-periodic solutions of the Dirac equation in a Reissner-Nordström black hole background
It is shown analytically that the Dirac equation has no normalizable, time-periodic solutions in a Reissner–Nordstrom black hole background; in particular, there are no static solutions of the Dirac
Cartan frames and the general relativistic Dirac equation.
The Dirac equation for spin‐½ particles in curved space‐time is formulated using Cartan calculus. Unlike previous formulations, this method is easy to use because it expresses the Dirac equation in
