A replica trick computation of the free energy requires an analytic continuation to zero replicas which is not well understood and appears to … Read More

Abstract:“I will argue that a sufficiently large spatial region in a bubble universe has an entanglement island surrounding it. This island arises due to mandatory collisions with adjacent AdS bubbles. The Unruh radiation from the accelerating domain walls plays a key role in making the bulk entropy term compete with the area term.
