Horizon Instability of the Extremal BTZ Black Hole
Samuel E. Gralla, Arun Ravishankar, Peter Zimmerman
We study real-time propagation of a massive scalar field on the extremal BTZ black hole spacetime, focusing on the Aretakis instability of the event horizon. We obtain a simple tim…

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…
