Nonlinear electrodynamics in Kerr-Newman-NUT- spacetime: exact solutions, horizons, and energy conditions
Oscar Galindo-Uriarte, Nora Breton, Claus Lämmerzahl +1
We construct two exact nonlinear-electrodynamic generalizations of the Kerr-Newman-NUT- spacetime. Imposing alignment between the principal directions of the electromagnetic fie…
