Amplified EFT corrections near exceptional QNMs
William L. Boyce, Jorge E. Santos
We show that the ordinary expansion of EFT corrections to individual QNM frequencies breaks down at an exceptional QNM, and that these corrections become enhanced for near-exceptio…

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…
