The point spectrum of the Dirac Hamiltonian on the zero-gravity Kerr-Newman spacetime (2111.01960v1)

Abstract: In this short paper, we review the Dirac equation on the zero-gravity Kerr-Newman spacetime. Our main objective is to provide a correspondence between the classification of the bound states for the zGKN spectrum and the usual hydrogenic states $1s_{1/2}$, $2s_{1/2}$, etc. of the Hydrogen atom.
