Hoffmann-Infeld black-hole solutions in Lovelock gravity

Mostrar todas las versiones(2)

Five-dimensional black holes are studied in Lovelock gravity coupled to Hoffmann-Infeld nonlinear electrodynamics. It is shown that some of these solutions present a double peak behaviour of the temperature as a function of the horizon radius. This feature suggests that the evaporation process, thou...
