Twirled Perfect Tensor Networks: Computationally covariant holographic tensor networks
Gurbir Arora, Matthew Headrick, Albion Lawrence +3
We define a novel class of tensor networks motivated by the Python's Lunch Conjecture (PLC) in local tensor network models of the black hole interior. We start from the observation…
Quantum Bit Threads and the Entropohedron
Matthew Headrick, Sreeman Reddy Kasireddy, Andrew Rolph
We derive several new quantum bit thread prescriptions for holographic entanglement entropy, equivalent for static states to the quantum extremal surface formula. Our new prescript…
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…
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…
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…
Entangled universes
Divij Gupta, Matthew Headrick, Martin Sasieta
We propose a generalization of the RT and HRT holographic entanglement entropy formulas to spacetimes with asymptotically Minkowski as well as asymptotically AdS regions. We postul…
