Constraints on cosmologies inside black holes (2022)
Journal Article
Fallows, S., & Ross, S. F. (2022). Constraints on cosmologies inside black holes. Journal of High Energy Physics, 2022(5), Article 094. https://doi.org/10.1007/jhep05%282022%29094

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, having a smooth Euclidean solution where the brane does not self-in... Read More about Constraints on cosmologies inside black holes.

Islands and mixed states in closed universes (2021)
Journal Article
Fallows, S., & Ross, S. F. (2021). Islands and mixed states in closed universes. Journal of High Energy Physics, 2021(7), Article 22. https://doi.org/10.1007/jhep07%282021%29022

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 multiboundary wormhole geometries as a model to explore what happens when the non... Read More about Islands and mixed states in closed universes.

Making near-extremal wormholes traversable (2020)
Journal Article
Fallows, S., & Ross, S. F. (2020). Making near-extremal wormholes traversable. Journal of High Energy Physics, 2020(12), Article 44. https://doi.org/10.1007/jhep12%282020%29044

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 in the extremal limit of the black hole. The black holes have finite e... Read More about Making near-extremal wormholes traversable.
