We study the holographic dual of a topological symmetry operator in the context of the
AdS/CFT correspondence. Symmetry operators arise from topological field theories …

A bstract We study Renyi entropies S n in quantum error correcting codes and compare the
answer to the cosmic brane prescription for computing\({\tilde {S}} _n\equiv {n}^ 2 {\partial} …

Motivated by the ability to consistently apply the Ryu-Takayanagi prescription for general
convex surfaces and the relationship between entanglement and geometry in tensor …

The Ryu-Takayanagi (RT) formula has been a key ingredient in our understanding of
holography. Recent work on TT deformations has also boosted our understanding of …

Motivated by the understanding of holography as realized in tensor networks, we develop a
bulk procedure that can be interpreted as generating a sequence of coarse-grained …

The past decade has seen a tremendous effort toward unraveling the relationship between
entanglement and emergent spacetime. These investigations have revealed that …

Holographic screens are codimension-one hypersurfaces that extend the notion of apparent
horizons to general (non-black hole) spacetimes and that display interesting thermodynamic …

A bstract We prove a new, large family of area laws in general relativity, which apply to
certain classes of untrapped surfaces that we dub generalized holographic screens. Our …

We define the coarse-grained entropy of a “normal” surface σ, ie, a surface that is neither
trapped nor antitrapped. Following Engelhardt and Wall, the entropy is defined in terms of …

A bstract The butterfly velocity characterizes the spread of correlations in a quantum system.
Recent work has provided a method of calculating the butterfly velocity of a class of …
