Superconformal indices and black hole saddles
Maciej Kolanowski, Donald Marolf, Zi-Yue Wang +1
The AdS/CFT correspondence implies that the superconformal index in SU(N) supersymmetric Yang-Mills theory can be computed using the dual bulk theor…
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…
How to tame your (black hole) saddles: Lessons from the Lorentzian Gravitational Path Integral
Maciej Kolanowski, Donald Marolf
We resolve a puzzle associated with the spherically-symmetric sector of the AdS Einstein-Maxwell partition function with inverse temperature . Since charge is quantized, th…
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…
Looking at extremal black holes from very far away
Maciej Kolanowski, Donald Marolf, Ilija Rakic +2
Near-extremal black holes are subject to large quantum effects, which modify their low-temperature thermodynamic behavior. Hitherto, these quantum effects were analyzed by separati…
Extended JT supergravity and random matrix models: The power of the string equation
Clifford V. Johnson, Maciej Kolanowski
A number of supersymmetric Jackiw-Teitelboim (JT) gravity theories are known to be described (in the Euclidean path integral formulation) by double-scaled random matrix models. Suc…
