Supersmoothing through Slow Contraction
arXiv:2006.01172 · doi:10.1016/j.physletb.2020.135690
Abstract
Performing a fully non-perturbative analysis using the tools of numerical general relativity, we demonstrate that a period of slow contraction is a `supersmoothing' cosmological phase that homogenizes, isotropizes and flattens the universe both classically and quantum mechanically and can do so far more robustly and rapidly than had been realized in earlier studies.
