String Theory seminar - Ioannis Papadimitriou Seminar

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.
