Expansion of the universe from a 5D vacuum within a nonperturbative scalar field formalism

TL;DR

This paper investigates the universe's expansion driven by a quantum scalar field during inflation, utilizing a novel nonperturbative formalism based on a five-dimensional vacuum to understand its dynamics.

Contribution

It introduces a nonperturbative 5D formalism to analyze scalar field-driven inflation, providing new insights into early universe expansion mechanisms.

Findings

Demonstrates the applicability of 5D vacuum formalism to inflationary dynamics

Provides a detailed description of scalar field behavior during different cosmic epochs

Suggests potential implications for higher-dimensional cosmological models

Abstract

We study the dynamics of the quantum scalar field responsible for inflation in different epochs of the evolution of the universe by using a recently introduced nonperturbative formalism from a 5D apparent vacuum.
