Quasinormal modes and quantum black hole interiors
Chiara Coviello, Ansh Gupta, Robie A. Hennigar +2
Quasinormal modes (QNMs) of black hole perturbations in the large overtone limit, namely, asymptotic QNMs, are highly sensitive to a black hole's interior geometry. We probe the si…
Looking inside a quantum black hole
Chiara Coviello, Ansh Gupta, Robie A. Hennigar +2
Quantum effects are expected to modify a black hole's interior structure, particularly near the singularity. We show how to extract the scaling exponent of the singularity from the…
Gravitational index of the D1-D5-P black string
Silvia Georgescu, Sameer Murthy, Andrew Svesko
We present saddle-points of the Euclidean Gravitational Path Integral (GPI) corresponding to the supersymmetric index of the D1-D5-P black string. These saddles are complex, supers…
The Stretched Horizon Limit
Dionysios Anninos, Damián A. Galante, Silvia Georgescu +2
We consider four-dimensional general relativity with a positive cosmological constant, , in the presence of a boundary, , of finite spatial size. The boundary is located near…
Quantum censors: backreaction builds horizons
Antonia M. Frassino, Robie A. Hennigar, Juan F. Pedraza +1
Cosmic censorship posits spacetime singularities remain concealed behind event horizons, preserving the determinism of General Relativity. While quantum gravity is expected to reso…
Conformal boundaries near extremal black holes
Damián A. Galante, Chawakorn Maneerat, Andrew Svesko
We examine four dimensional, near-extremal black hole solutions in the presence of a finite boundary obeying conformal boundary conditions, where the conformal class of the induced…
The landscape of complexity measures in 2D gravity
Elena Cáceres, Rafael Carrasco, Vaishnavi Patil +2
We investigate the broad landscape of holographic complexity measures for theories dual to two-dimensional (2D) dilaton gravity. Previous studies have largely focused on the comple…
Quantum induced superradiance
Casey Cartwright, Umut Gürsoy, Juan F. Pedraza +1
Superradiance, the phenomenon enabling energy extraction through radiation amplification, is not universal to all black holes. We show that semi-classical backreaction can induce s…
Nucleation of charged quantum de-Sitter black holes
Ana Climent, Robie A. Hennigar, Emanuele Panella +1
We construct charged, static black holes in three-dimensional de Sitter (dS) space that exactly account for semi-classical backreaction effects due to quantum conformal matte…

Sergio E. Aguilar-Gutierrez, Andrew Svesko, Manus R. Visser
We revisit the formalism of deformations for quantum theories that are holographically dual to two-dimensional dilaton-gravity theories with Dirichlet…
Three-dimensional quantum black holes: a primer
Emanuele Panella, Juan F. Pedraza, Andrew Svesko
We review constructions of three-dimensional `quantum' black holes. Such spacetimes arise via holographic braneworlds and are exact solutions to an induced higher-derivative theory…
Quantum inequalities for quantum black holes
Antonia M. Frassino, Robie A. Hennigar, Juan F. Pedraza +1
We formulate spacetime inequalities applicable to quantum-corrected black holes to all orders of backreaction in semiclassical gravity. Namely, we propose refined versions of the q…
Liouville gravity at the end of the world: Deformed defects in AdS/BCFT
Dominik Neuenfeld, Andrew Svesko, Watse Sybesma
We study shape deformations of two-dimensional end-of-the-world (ETW) branes, such as those in bottom-up models of two-dimensional holographic boundary conformal field theories (BC…

Jani Kastikainen, Andrew Svesko
We present a new derivation of gravitational entropy functionals in higher-curvature theories of gravity using corner terms that are needed to ensure well-posedness of the variatio…

We show backreaction of quantum fields on black hole geometries can trigger new thermal phase transitions. Specifically, we study the phase behavior of the three-dimensional quantu…
Gravitation from optimized computation: Einstein and beyond
Rafael Carrasco, Juan F. Pedraza, Andrew Svesko +1
A new principle in quantum gravity, dubbed spacetime complexity, states that gravitational physics emerges from spacetime seeking to optimize the computational cost of its quantum…

Higher-dimensional origin of extended black hole thermodynamics
Antonia M. Frassino, Juan F. Pedraza, Andrew Svesko +1
Holographic braneworlds are used to present a higher-dimensional origin of extended black hole thermodynamics. In this framework, classical, asymptotically anti-de Sitter black hol…
The minus sign in the first law of de Sitter horizons
Batoul Banihashemi, Ted Jacobson, Andrew Svesko +1
Due to a well-known, but curious, minus sign in the Gibbons-Hawking first law for the static patch of de Sitter space, the entropy of the cosmological horizon is reduced by the add…
Membrane nucleation rates from holography
Maite Arcos, Willy Fischler, Juan F. Pedraza +1
Membrane nucleation, a higher dimensional analog of the Schwinger effect, is a useful toy model for vacuum decay. While a non-perturbative effect, the computation of nucleation rat…
Black holes in dS
Roberto Emparan, Juan F. Pedraza, Andrew Svesko +2
In three-dimensional de Sitter space classical black holes do not exist, and the Schwarzschild-de Sitter solution instead describes a conical defect with a single cosmological hori…
Computing spacetime
Juan F. Pedraza, Andrea Russo, Andrew Svesko +1
Inspired by the universality of computation, we advocate for a principle of spacetime complexity, where gravity arises as a consequence of spacetime optimizing the computational co…
