Black Hole Thermodynamics without Black Hole Solutions (opens in new tab)

Author(s): Meng-Nan Yang, Guan-Yi Lu, and H. LüWe 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 theor…[Phys. Rev. Lett. 136, 251403] Published Tue Jun 23, 2026
