Quantum Evolution of the Bianchi Type I Model

TL;DR

This paper investigates the quantum behavior of a flat anisotropic universe model with a scalar field, revealing phenomena like wave reflection and bouncing, leading to inflation and isotropization.

Contribution

It introduces a quantum cosmological analysis of Bianchi Type I models, highlighting the effects of potential barriers and walls on universe evolution.

Findings

Wave function reflection occurs at potential barriers.

Universe undergoes a bounce off potential walls.

Exponential inflation reduces anisotropy.

Abstract

The behaviour of the flat anisotropic model of the Universe with a scalar field is explored within the framework of quantum cosmology. The principal moment of the account of an anisotropy is the presence either negative potential barrier or positive repelling wall. In the first case occur the above barrier reflection of the wave function of the Universe, in the second one there is bounce off a potential wall. The further evolution of the Universe represents an exponential inflating with fast losses of an anisotropy and approach to the standard cosmological scenario.
