Tripartite Form Universality in Holographic Entropy Inequalities
Veronika E. Hubeny, Yu Liu
To elucidate the meaning of holographic entropy inequalities (beyond subadditivity) which characterize the entanglement structure of geometric states in holography, arXiv:2309.0629…
Combinatorial properties of holographic entropy inequalities
Guglielmo Grimaldi, Matthew Headrick, Veronika E. Hubeny +1
A holographic entropy inequality (HEI) is a linear inequality obeyed by Ryu-Takayanagi holographic entanglement entropies, or equivalently by the minimum cut function on weighted g…
On the construction of graph models realizing given entropy vectors
Veronika E. Hubeny, Massimiliano Rota
We present an efficient algorithm for the construction of a holographic simple tree graph model that realizes a given entropy vector, subject to a specific ``chordality'' condition…
A new characterization of the holographic entropy cone
Guglielmo Grimaldi, Matthew Headrick, Veronika E. Hubeny
Entanglement entropies computed using the holographic Ryu-Takayanagi formula are known to obey an infinite set of linear inequalities, which define the so-called RT entropy cone. T…
Minimax surfaces and the holographic entropy cone
Brianna Grado-White, Guglielmo Grimaldi, Matthew Headrick +1
We study and prove properties of the minimax formulation of the HRT holographic entanglement entropy formula, which involves finding the maximal-area surface on a timelike hypersur…
Correlation hypergraph: a new representation of a quantum marginal independence pattern
Veronika E. Hubeny, Massimiliano Rota
We continue the study of the quantum marginal independence problem, namely the question of which faces of the subadditivity cone are achievable by quantum states. We introduce a ne…
