Theory Seminar (High Energy/Cosmology)

- Replica wormholes, the black hole information paradox, and cosmology
- Time: 2:00 pm
- Place: For zoom link, sign up at: https://groups.google.com/a/g-groups.wisc.edu/d/forum/theoryseminars/join
- Speaker: Edgar Shaghoulian, University of Pennsylvania
- Abstract: I will introduce the black hole information paradox and briefly review the role that replica wormholes play in obtaining black hole evolution consistent with unitarity. I will then discuss general consistency conditions that guide the search for such nontrivial saddles in the gravitational path integral, with several examples in cosmological spacetimes.
- Host: Lars Aalsma
