The Baby Universe is Fine and the CFT Knows It: On Holography for Closed Universes
Stefano Antonini, Pratik Rath, Martin Sasieta +2
Big bang/big crunch closed universes can be realized in AdS/CFT, even though they lack asymptotically AdS boundaries. With enough bulk entanglement, the bulk Hilbert space of a clo…

Asymptotic T-duality in three dimensions
Stéphane Detournay, José Figueroa, Alejandro Vilar López
In (super)gravity theories, T-duality relates solutions with an exact isometry which can have wildly different asymptotic behaviors: a well-known example is the duality between BTZ…

Universal Construction of Black Hole Microstates
Ana Climent, Roberto Emparan, Javier M. Magan +2
We refine and extend a recent construction of sets of black hole microstates with semiclassical interiors that span a Hilbert space of dimension , where is the black hole…
