Semi-local Quantum Criticality and the Instability of Extremal Planar Horizons
Samuel E. Gralla, Arun Ravishankar, Peter Zimmerman
We show that the Aretakis instability of compact extremal horizons persists in the planar case of interest to holography and discuss its connection with the emergence of "semi-loca…

Scaling and Universality in Extremal Black Hole Perturbations
Samuel E. Gralla, Peter Zimmerman
We show that the emergent near-horizon conformal symmetry of extremal black holes gives rise to universal behavior in perturbing fields, both near and far from the black hole horiz…

Perturbations of Extremal Kerr Spacetime: Analytic Framework and Late-time Tails
Marc Casals, Peter Zimmerman
We develop a complete and systematic analytical approach to field perturbations of extremal Kerr spacetime based on the formalism of Mano, Suzuki and Takasugi (MST) for the Teukols…
