Title
Quantum Black Holes in Non-Linear Electrodynamics
Abstract
Black holes are fascinating cosmic objects which require both relativistic and quantum theories for their accurate description. Since full quantum gravity still has not been discovered, there have been attempts to study it in simplified frameworks, namely in semi-classical gravity, where the geometry of the spacetime is taken to be classical while the energy-momentum tensor is treated as a quantum object. However, even semi-classical gravity is hard to solve, and perturbative methods have been successful only in limited cases. Fortunately, AdS/CFT correspondence admits a promising approach to this problem using holographic renormalization and braneworld holography. The idea is to identify and get rid of the divergences in the action by inserting a brane into the bulk spacetime. We find out that a lower-dimensional higher-curvature theory of gravity is induced on the brane, and its solutions are dubbed quantum black holes = quantum-corrected black holes in all orders of backreaction. These black holes are located on the brane and are accelerating with respect to the bulk. In this talk, I will review this approach and show novel results for electrically charged quantum black holes described by non-linear electrodynamics
