Chaos in a tunneling universe
Martin Bojowald, Ari Gluckman

TL;DR
This paper demonstrates that a quasiclassical tunneling universe model exhibits chaotic dynamics due to non-adiabatic quantum effects, suggesting a broader range of initial conditions can lead to large expanding universes.
Contribution
It introduces new quasiclassical methods to analyze chaos in tunneling universe models, highlighting the role of non-adiabatic quantum features.
Findings
Chaotic behavior identified via fractal dimension analysis.
Chaos arises from non-adiabatic quantum dynamics.
Broader initial conditions can lead to universe expansion.
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.
