Chaos in a tunneling universe
arXiv:2307.03145 · doi:10.1088/1475-7516/2023/11/052
Abstract
A recent quasiclassical description of a tunneling universe model is shown to exhibit chaotic dynamics by an analysis of fractal dimensions in the plane of initial values. This result relies on non-adiabatic features of the quantum dynamics, captured by new quasiclassical methods. Chaotic dynamics in the early universe, described by such models, implies that a larger set of initial values of any large expanding branch can be probed.
