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:…
The quantum marginal independence problem
Sergio Hernández-Cuenca, Veronika E. Hubeny, Mukund Rangamani +1
We investigate whether the presence or absence of correlations between subsystems of an N-partite quantum system is solely constrained by the non-negativity and monotonicity of mut…
