Cornering gravitational entropy
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…
Gravitational Rényi entropy from corner terms
Jani Kastikainen, Andrew Svesko
We provide a consistent first principles prescription to compute gravitational Rényi entropy using Hayward corner terms. For Euclidean solutions to Einstein gravity, we compute Rén…
Reentrant phase transitions of quantum black holes
Antonia M. Frassino, Juan F. Pedraza, Andrew Svesko +1
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…
Quantum Kerr-de Sitter black holes in three dimensions
Emanuele Panella, Andrew Svesko
We use braneworld holography to construct a three-dimensional quantum-corrected Kerr-de Sitter black hole, exactly accounting for semi-classical backreaction effects due to a holog…
