Chaos in a tunneling universe

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 an expanding branch can be probed.

A recent study shows that a tunneling universe model exhibits chaotic dynamics through the analysis of fractal dimensions in the plane of initial values. This result is based on non-adiabatic features of quantum dynamics captured by new quasiclassical methods. The chaotic dynamics in the early universe, described by such models, allows for a larger range of initial values to be probed.
