Abstract: Holographic tensor networks model AdS/CFT, but so far they have been limited by involving only systems that are very different from gravity. Unfortunately, we cannot straightforwardly discretize gravity to incorporate it, because that would break diffeomorphism invariance. In this talk I will present a resolution, based on upcoming work with Ronak Soni and Annie Y. Wei. We construct a … Read More

Abstract: In the past few years, holography has served as a powerful tool in describing strong gravitational phenomena. Recently, several works have started to apply these tools to Big Bang-Big Crunch cosmologies. In this talk, I will describe the explicit construction of holographic 4D braneworld cosmologies and 4D eternally traversable wormholes by embedding End of the World (ETW) branes in 5D … Read More
