Conformal Field Theories and the Entropy of Black Holes

Christoph Keller

Visiting Assistant Professor
University of Arizona

Conformal field theories (CFTs) are quantum field theories that are invariant under angle-preserving transformations. Through the AdS/CFT correspondence, they can be used to describe gravity in anti-de Sitter spaces, for instance to describe the entropy of certain black holes. I will discuss new constructions of such CFTs and their thermodynamic properties, with a particular focus on phase transitions. I will also describe how modular forms play an important role in this approach.
