Algebraic structure in holographic tensor networks
Abhisek Sahu, Jeremy van der Heijden, Mark Van Raamsdonk +1
In a previous work 2511.21852, we explored the hypothesis that in general theories of quantum gravity, spacetime regions known as generalized entanglement wedges (introduced by Bou…
Factor Code Networks
Abhisek Sahu, Jeremy van der Heijden, Mark Van Raamsdonk +1
For a quantum code defined by an isometry , an operator map is a *-homomorphism from the space of operator…
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…

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…

Seraphim Jarov, Mark Van Raamsdonk
For a quantum system with Hilbert space of dimension and a set of Hermitian operators , a basic question is to understand the set $E_S \subset \m…
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…
Suggestions of decreasing dark energy from supernova and BAO data
Mark Van Raamsdonk, Chris Waddell
The potential energy from a time-dependent scalar field provides a possible explanation for the observed cosmic acceleration. In this paper, we investigate how data from supernova…

A large class of cosmologies have big-bang / big crunch spacetimes with time-symmetric backgrounds and asymptotically AdS Euclidean continuations suggesting a possible holog…
Enhanced Negative Energy with a Massless Dirac Field
Brian Swingle, Mark Van Raamsdonk
Motivated by traversable wormhole constructions that require large amounts of negative energy, we explore constraints on the amount of negative energy that can be carried by a free…

Stefano Antonini, Petar Simidzija, Brian Swingle +1
A large class of flat big bang - big crunch cosmologies with negative cosmological constant are related by analytic continuation to asymptotically AdS traversable wormholes with pl…

The positivity of relative entropy for spatial subsystems in a holographic CFT implies the positivity of certain quantities in the dual gravitational theory. In this note, we consi…
