Island mirages (2206.06144v2)
Published 13 Jun 2022 in hep-th and gr-qc
Abstract: We point out a loophole in the proof that the Island Finder conditions are sufficient for the existence of islands. We explore examples which satisfy the conditions, but have no islands, which we call island mirages. We also describe and give resolutions to two new puzzles associated with islands, including a direct tension with the quantum Bousso bound.
