An outsider's perspective on information recovery in de Sitter space
Entanglement islands play a crucial role in our understanding of how Hawking radiation encodes information in a black hole, but their relevance in cosmological spacetimes is less clear. In this talk, I review some aspects of entanglement islands in black holes, and present a protocol for information recovery in de Sitter space in two dimensions. This setup revolves around a two-dimensional model of gravity containing a domain wall that interpolates between de Sitter space and Rindler space. This talk is mainly based on the results of https://arxiv.org/abs/2210.12176. Online link: meet.google.com/gbj-tmns-err
