Black-hole solution in nonlinear electrodynamics with the maximum allowable symmetries

Abstract
Abstract The nonlinear Maxwell Lagrangian preserving both conformal and SO(2) duality-rotation invariance has been introduced very recently. Here, in the context of Einstein’s theory of gravity minimally coupled with this nonlinear electrodynamics, we obtain a black hole solution which is the Reissner–Nordström black hole with one additional parameter that is coming from the nonlinear theory. We employ the causality and unitarity principles to identify an upper bound for this free parameter. The effects of this parameter on the physical properties of the black hole solution are investigated.
