Statistical mechanics of charged black holes in induced Einstein-Maxwell gravity - art. no. 064010

The statistical origin of the entropy of charged black holes in models of i nduced Einstein-Maxwell gravity is investigated. The constituents inducing the Einstein-Maxwell action are charged and interact with an external gauge potential. This new feature, however, does not change the divergences of t he statistical-mechanical entropy of the constituents near the horizon. It is demonstrated that the mechanism of the generation of Bekenstein-Hawking entropy in induced gravity is universal and it is basically the same for ch arged and neutral black holes. The concrete computations are carried out fo r induced Einstein-Maxwell gravity with a negative cosmological constant in three space-time dimensions.
