HoloBHC is a Starting Grant ERC project (2013), led by Geoffrey Compère (Mathematics and Theoretical Physics Department, Faculty of Sciences)

String theory provides with a consistent framework which combines quantum mechanics and gravity. Two grand challenges of fundamental physics - building realistic models of black holes and cosmologies - can be addressed in this framework thanks to novel holographic methods. The Geoffrey Compère's first objective is building the first model in string theory of an extremal black hole. If successful, this program will pave the way to a description of quantum gravity effects that have been conjectured to occur close to the horizon of very fast rotating black holes. His second objective is to derive new universal properties of the cosmological horizon of de Sitter spacetime using tools inspired from the gauge/gravity correspondence. These results will contribute to understand its remarkable entropy, which, according to the standard model of cosmology, bounds the entropy of our observable universe.
