Replica wormholes and the information paradox

12.11.2020 14:00 – 15:00

I will review recent progress on the black hole information puzzle involving the appearance of "islands" in the black hole interior. The islands arise from the replica trick used to calculate the entropy of Hawking radiation. This entropy receives large non-perturbative corrections from gravitational instantons called replica wormholes, which connect multiple copies of the black hole through their interiors. I will also discuss cosmological models where wormholes could be relevant.
