Lovelock black holes with double-logarithmic electrodynamics source

Abstract

This work examines the magnetized black holes of Lovelock gravity in the presence of double-logarithmic electrodynamics. In this context, the Lovelock polynomial is found and the accompanying thermodynamic quantities, such as mass, entropy, Hawking temperature, and heat capacity, are determined. This new model of nonlinear electrodynamics is used to calculate the black hole solutions of Einstein, Gauss–Bonnet and third-order Lovelock gravities as well. The impacts of the double-logarithmic electromagnetic field on the black hole thermodynamics in these particular theories are examined and the regions of horizon radius that correspond to the local thermodynamic stability are highlighted.
