Constraints on cosmologies inside black holes
Seamus Fallows, Simon F. Ross
We study the construction of holographic models with closed FRW cosmologies on the worldvolume of a constant-tension brane inside a Schwarzschild-AdS black hole. In dimensions d>2,…

Islands and mixed states in closed universes
Seamus Fallows, Simon F. Ross
We investigate the appearance of islands when a closed universe with gravity is entangled with a non-gravitating quantum system. We use braneworlds in three-dimensional multibounda…

Making near-extremal wormholes traversable
Seamus Fallows, Simon F. Ross
We construct a traversable wormhole from a charged AdS black hole by adding a coupling between the two boundary theories. We investigate how the effect of this deformation behaves…
