Algebras for generalized entanglement wedges
Abhisek Sahu, Jeremy van der Heijden, Mark Van Raamsdonk +1
In asymptotically AdS spacetimes, the mathematical structure of the set of entanglement wedges reflects the algebraic structure of the underlying holographic description. For more…
Finite entropy sums in quantum field theory
Mark Van Raamsdonk
Entropies associated with spatial subsystems in conventional local quantum field theories are typically divergent when the spatial regions have boundaries. However, in certain line…
Cosmology with non-conformal holographic matter
Mark Van Raamsdonk, Rana Zibakhsh
We investigate the effect on cosmological evolution of a strongly coupled quantum field that undergoes renormalization group flow from a UV CFT to an IR CFT. The field theory is de…
Building up spacetime with quantum entanglement
Mark Van Raamsdonk
In this essay based on 0907.2939, we argue that the emergence of classically connected spacetimes is intimately related to the quantum entanglement of degrees of freedom in a non-p…
Holographic black hole cosmologies
Abhisek Sahu, Mark Van Raamsdonk
We describe and study a holographic construction of big-bang / big-crunch cosmological spacetimes where the matter consists of a lattice of black holes. The cosmological spacetime…
