On the discrete Dirac spectrum of a point electron in the zero-gravity Kerr–Newman spacetime
On the discrete Dirac spectrum of a point electron in the zero-gravity Kerr–Newman spacetime
The discrete spectrum of the Dirac operator for a point electron in the maximal analytically extended Kerr–Newman spacetime is determined in the zero-G limit (zGKN), under some restrictions on the electrical coupling constant and on the radius of the ring-singularity of the zGKN spacetime. The spectrum is characterized by a …
