A single geometry from an all-genus expansion in quantum gravity
Sergio Hernández-Cuenca, Nico Valdes-Meller, Wayne Wei-en Weng
We report on an instance in quantum gravity where a topological expansion resums into an effective description on a single geometry. The original theory whose gravitational path in…

Wormholes and Factorization in Exact Effective Theory
Sergio Hernández-Cuenca
We study the general framework of effective theories obtained via exact path integration of a complete theory over some sector of its degrees of freedom. Theories constructed this…

Holographic Entropy Inequalities and Multipartite Entanglement
Sergio Hernández-Cuenca, Veronika E. Hubeny, Frederic Jia
We study holographic entropy inequalities and their structural properties by making use of a judicious grouping of terms into certain multipartite information quantities. This allo…
