Axions Create Singularities on Extremal Horizons
Gary T. Horowitz, Maciej Kolanowski, Grant N. Remmen +1
We show that axions cause extremal black holes to have singular horizons. This is true for almost all values of the axion mass and coupling provided the black hole is rotating and…
After the Fluid: Subexponential Decay in AdS
John R. V. Crump, Jorge E. Santos
We study the late-time behaviour of nonlinear perturbations of Schwarzschild-AdS black branes and show that real-analytic initial data generically enter a regime controlled by…
EFT Corrections to Charged Black Hole Quasinormal Modes
William L. Boyce, Jorge E. Santos
We study the impact of higher-derivative corrections from Effective Field Theory on the quasinormal mode spectrum of Reissner-Nordström black holes. While previous work has explor…
Mixmaster chaos in an AdS black hole interior
Marine De Clerck, Sean A. Hartnoll, Jorge E. Santos
We derive gravitational backgrounds that are asymptotically Anti-de Sitter, have a regular black hole horizon and which deep in the interior exhibit mixmaster chaotic dynamics. The…
Self Gravitating Spinning String Condensates
Jorge E. Santos, Yoav Zigdon
In the context of the black hole/string transition, it is useful to produce Euclidean string backgrounds representing hot and self-gravitating strings. We utilise analytical and nu…
