Mixmaster universe: semiclassical dynamics and inflation from bouncing

TL;DR

This paper investigates the quantum Bianchi type IX cosmological model, analyzing its semi-classical dynamics through analytical and numerical methods to understand its potential role in early universe inflation and primordial structure formation.

Contribution

It provides a detailed analytical and numerical study of the quantum Bianchi IX model's semi-classical behavior and its implications for inflationary scenarios in early cosmology.

Findings

Semi-classical analysis supports inflationary behavior in the model.

Numerical simulations align with classical inflationary predictions.

Results suggest the model's relevance for primordial structure formation.

Abstract

In this work we explore the quantum Bianchi type IX-model, its semi-classical features, and its relevance in early cosmology to tentatively explain inflation and production of primordial structures. We specially focus on the analytical and numerical exploration of the dynamical system derived from the phase-space portraits. Afterwards we investigate the reliability of our results with regard to inflation and post inflation scenarii commonly accepted nowadays.
