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…
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…
Testing holographic entropy inequalities in 2+1 dimensions
Brianna Grado-White, Guglielmo Grimaldi, Matthew Headrick +1
We address the question of whether holographic entropy inequalities obeyed in static states (by the RT formula) are always obeyed in time-dependent states (by the HRT formula), foc…
Quantum Extremal Islands Made Easy, Part IV: Massive Black Holes on the Brane
Guglielmo Grimaldi, Juan Hernandez, Robert C. Myers
We study two-dimensional eternal black holes with non-zero mass, where each asymptotic boundary is in contact with a CFT on a circle, following the doubly holographic braneworld mo…
