Black Hole Thermodynamics without Black Hole Solutions
Abstract
We consider the string-theory-inspired Einstein-Maxwell-Maxwell-dilaton theory and show that we can derive the complete set of thermodynamic quantities of charged black holes without having to construct the black hole solutions. We argue that the technique can be applied more broadly to string theories, providing an accessible method for determining the thermodynamic properties of large classes of black holes for which exact solutions are typically unavailable.
