Hidden Conformal Symmetry and Quasi-normal Modes

Chen, Bin, Long, Jiang

Understand

We provide an algebraic way to calculate the quasi-normal modes of a black hole, which possesses a hidden conformal symmetry.

  • We construct an infinite tower of quasi-normal modes from the highest-weight mode, in a simple and elegant way.
  • For the scalar, the hidden conformal symmetry manifest itself in the fact that the scalar Laplacian could be rewritten in terms of the $SL(2,R)$ quadratic Casimir.
  • For the vector and the tensor, the hidden conformal symmetry acts on them through Lie derivatives.
