Event details
I will discuss a consistent Kaluza-Klein reduction of 5D Einstein gravity on warped S^2 x S^1 that includes the Myers-Perry or Kerr-AdS black holes with two equal angular momenta as special cases. The effective 2D theory admits an AdS2 vacuum corresponding to the extremal Kerr black hole. I will holographically derive the quantum effective action of the dual 1D theory in conformal perturbation theory around the extremal solution and will show how the presence of a conformal anomaly gives rise to the Schwarzian effective action. I will conclude with some comments on black hole thermodynamics.
Speaker information
Dr Ioannis Papadimitriou , KIAS. Dr Papadimitriou is a theoretical high energy physicist working on aspects of string theory, black holes and quantum field theory. He is particularly interested in the mathematical equivalence between strongly interacting quantum field theories and theories of quantum gravity, known as holographic duality. His recent and ongoing work includes the application of holographic dualities to the study of strongly coupled systems in condensed matter physics, the emergence of gravity from the exact renormalization group of strongly coupled quantum field theories, asymptotic spacetime symmetries, boundary conditions for quantum gravity, as well as anomalies in supersymmetric gauge theories and their implications for localization techniques.
