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…
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…
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…
Holographic motivations and observational evidence for decreasing dark energy
Mark Van Raamsdonk, Chris Waddell
Negative lambda gravitational effective field theories dual to holographic CFTs have potentially realistic cosmological solutions. Generic cosmological solutions of these effective…
Bubbles of cosmology in AdS/CFT
Abhisek Sahu, Petar Simidzija, Mark Van Raamsdonk
Gravitational effective theories associated with holographic CFTs have cosmological solutions, which are typically big-bang / big-crunch cosmologies. These solutions are not asympt…
