Living on the Edge of Effective Field Theory: Near-Extremal Black Holes in Quadratic Gravity

Kelvin Ka-Ho Lam, Gary T. Horowitz, Nicolás Yunes

Near-extremal black holes can amplify higher-derivative corrections to general relativity, making them sharp probes of the perturbative control of gravitational effective field the…

Dirichlet walls and the end of time

Hanako Helton, Gary T. Horowitz, Donald Marolf

We study evolution in Einstein-Hilbert gravity with Dirichlet boundary conditions imposed on a finite surface. We argue that there are open sets of initial data where such evolutio…

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…

Frozen Firewall: Generic Singularity Formation on an Extremal Horizon

Gary T. Horowitz, Maciej Kolanowski, Jorge E. Santos

It is known that linearized perturbations of extremal black holes result in growing curvature on the horizon. However, nonlinear perturbations typically do not evolve to extremal b…

Constraints are not enough

Gary T. Horowitz, Donald Marolf, Jorge E. Santos

The Euclidean Einstein-Hilbert action is well-known to be unbounded below and thus to raise many questions regarding the definition of the gravitational path integral. A variety of…

Counting States of Black Strings with Traveling Waves II

Gary T. Horowitz, Donald Marolf

We extend our recent analysis of the entropy of extremal black strings with traveling waves. We previously considered waves carrying linear momentum on black strings in six dimensi…
