Open AccessPage curves and replica wormholes from random dynamics
We show how to capture both the non-unitary Page curve and replica wormhole-like contributions that restore unitarity in a toy quantum system with random dynamics. The motivation is to find the simplest dynami...

Open AccessIsland mirages
We point out a loophole in the proof that the Island Finder conditions [1] are sufficient for the existence of islands. We explore examples which satisfy the conditions, but have no islands, which we call island ...

Open AccessSpacetime as a quantum circuit
We propose that finite cutoff regions of holographic spacetimes represent quantum circuits that map between boundary states at different times and Wilsonian cutoffs, and that the complexity of those quantum ci...

Open AccessBit threads in higher-curvature gravity
We generalize holographic bit threads to bulk theories with a gravitational action containing higher-curvature terms. Bit threads are a reformulation of holographic entanglement entropy, where the entropy is g...

Open AccessEntanglement shadows in LLM geometries
We find a new example of an asymptotically AdS5 × S5 geometry which has an entanglement shadow: that is, a region of spacetime which no Ryu-Takayanagi minimal surface enters. Our example is a particular case of t...
