Quasitopological Reissner-Nordström black holes
Abstract
We consider Reissner-Nordström solutions in quasitopological gravity, obtaining exact solutions to the field equations yielding charged quasitopological black holes. We study their thermodynamic behavior over a range of parameters that yield ghost-free and stable space times. We find that a sufficiently negative quasitopological parameter can yield black holes with two horizons, even for zero charge. We discuss the thermodynamic stability for the class of solutions we obtain. We also describe the structure of exact charged solutions to kth-order quasitopological gravity.
