Extremal black holes with wiggles
  OKC/Nordita High-Energy Physics Theory seminar

Monday 05 October 2015
from 13:15 to 14:15
at 122:026
Speaker : Geoffrey Compère (ULB )
Abstract : Symmetries are crucial in physics. Here I will develop the concept of symplectic symmetry for Einstein gravity, which is an extension of the concept of asymptotic symmetries. I will then show that the throat of the extremal Kerr black hole admits symplectic symmetries, which leads to an infinite number of conserved charges which form a Virasoro algebra in 4 dimensions and a novel generalized Virasoro algebra in higher dimensions. I will build explicitly the geometries that carry these charges, the so-called "descendants" of the extremal black hole, in the near-horizon region.
