Cosmologies inside hyperbolic black holes (2022)
Journal Article
Ross, S. F. (2022). Cosmologies inside hyperbolic black holes. Journal of High Energy Physics, 2022(11), Article 168. https://doi.org/10.1007/jhep11%282022%29168

Models with closed FRW cosmologies on the worldvolume of a constant-tension brane inside a black hole provide an interesting setup for studying cosmology holographically. However, in more than two worldvolume dimensions, there are limitations on such... Read More about Cosmologies inside hyperbolic black holes.

Going beyond ER=EPR in the SYK model (2022)
Journal Article
Berkooz, M., Brukner, N., Ross, S. F., & Watanabe, M. (2022). Going beyond ER=EPR in the SYK model. Journal of High Energy Physics, 2022(8), Article 51. https://doi.org/10.1007/jhep08%282022%29051

We discuss generalizations of the TFD to a density matrix on the doubled Hilbert space. We suggest that a semiclassical wormhole corresponds to a certain class of such density matrices, and specify how they are constructed. Different semi-classical p...

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.

Towards traversable wormholes from force-free plasmas (2022)
Journal Article
Iqbal, N., & Ross, S. F. (2022). Towards traversable wormholes from force-free plasmas. SciPost Physics, 12(3), Article 086. https://doi.org/10.21468/scipostphys.12.3.086

The near-horizon region of magnetically charged black holes can have very strong magnetic fields. A useful low-energy effective theory for fluctuations of the fields, coupled to electrically charged particles, is force-free electrodynamics. The low e...
