Quantum origin of pre-big bang collapse from Induced Matter theory of gravity

TL;DR

This paper explores the quantum dynamics of a scalar field in a pre-big bang collapse model, revealing that quantum effects fundamentally influence the universe's evolution within an induced matter gravity framework.

Contribution

It demonstrates that the quantum contributions of an effective 4D scalar field are the sole origin of the system's evolution in a non-perturbative collapsing universe model.

Findings

Quantum effects drive the evolution of the scalar field.

The model links quantum contributions to pre-big bang collapse dynamics.

Induced matter theory explains the quantum origin of cosmological collapse.

Abstract

We revisit a collapsing pre-big-bang model of the universe to study with detail the non-perturbative quantum dynamics of the dispersal scalar field whose dynamics becomes from the dynamical foliation of test massless scalar field $\phi$ on a 5D Riemann-flat metric, such that the extra space-like coordinate is noncompact. The important result here obtained is that the evolution of the system, which is described thorough the equation of state has the unique origin in the quantum contributions of the effective 4D scalar field.
