Nonlinear electrodynamics coupled to gravity; regular rotating electrically charged black holes and solitons
Source-free equations of nonlinear electrodynamics minimally coupled to gravity (NED-GR) admit regular axially symmetric asymptotically Kerr-Newman solutions which describe electrically charged rotating black holes and spinning solitons. Asymptotic analysis of solutions shows the existence of de Sitter vacuum interior which has the properties of a perfect conductor and an ideal diamagnetic. The Kerr ring singularity (a naked singularity in the case without horizons) is replaced with a superconducting current which serves as a nondissipative source of the Kerr-Newman fields and can be responsible for an unlimited life time of a spinning object.
