BTZ dilatonic black holes coupled to Maxwell and Born-Infeld electrodynamics

Abstract

Motivated by string theory corrections of dilatonic gravity and Born-Infeld nonlinear electromagnetic field, we consider the BTZ black holes with these two generalizations. It will be shown that the generalization to dilatonic gravity introduces novel properties into thermodynamics of the black holes which were absent in the purely gravity case. Furthermore, the possibility of tuning out part of the dilatonic effects is explored in the Born-Infeld generalization.
