Choptuik scaling and quasinormal modes in the anti-de Sitter space/conformal-field theory correspondence

We establish an exact connection between the Choptuik scaling parameter for the three-dimensional Banados-Teitelboim-Zanelli black hole, and the imaginary part of the quasinormal frequencies for scalar perturbations. Via the anti-de Sitter space/conformal-field theory correspondence, this leads to an interpretation of Choptuik scaling in terms of the time scale for return to equilibrium of the dual conformal field theory.
