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…
Kerr Black Hole Ringdown in Effective Field Theory
William L. Boyce, Jorge E. Santos
We develop a systematic effective field theory calculation of the quasinormal modes of Kerr black holes valid for arbitrary spin, providing model-independent corrections to their r…
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…
