The Symmetrized Holographic Entropy Cone
Matteo Fadel, Sergio Hernández-Cuenca
The holographic entropy cone (HEC) characterizes the entanglement structure of quantum states which admit geometric bulk duals in holography. Due to its intrinsic complexity, to da…
Quantum Extremal Surfaces and the Holographic Entropy Cone
Chris Akers, Sergio Hernández-Cuenca, Pratik Rath
Quantum states with geometric duals are known to satisfy a stricter set of entropy inequalities than those obeyed by general quantum systems. The set of allowed entropies derived u…
Topological Link Models of Multipartite Entanglement
Ning Bao, Newton Cheng, Sergio Hernández-Cuenca +1
We introduce a novel model of multipartite entanglement based on topological links, generalizing the graph/hypergraph entropy cone program. We demonstrate that there exist link rep…
Conformal Rigidity from Focusing
Åsmund Folkestad, Sergio Hernández-Cuenca
The null curvature condition (NCC) is the requirement that the Ricci curvature of a Lorentzian manifold be nonnegative along null directions, which ensures the focusing of null geo…
Boundary Causality Violating Metrics in Holography
Sergio Hernández-Cuenca, Gary T. Horowitz, Gabriel Treviño +1
Even for holographic theories that obey boundary causality, the full bulk Lorentzian path integral includes metrics that violate this condition. This leads to the following puzzle:…
On the foundations and extremal structure of the holographic entropy cone
David Avis, Sergio Hernández-Cuenca
The holographic entropy cone (HEC) is a polyhedral cone first introduced in the study of a class of quantum entropy inequalities. It admits a graph-theoretic description in terms o…
