Is emergent scenario in the early Universe a consequence of the dynamics of real scalar field particle ?

TL;DR

This paper investigates whether the emergent scenario of the early Universe can be explained through the dynamics of a real scalar field particle within quantum field theory, aiming to provide a physical foundation for non-singular cosmic origins.

Contribution

It offers a quantum field theoretical perspective to justify the emergent universe scenario, connecting non-singular cosmic evolution with scalar field dynamics.

Findings

Proposes a scalar field model consistent with emergent universe scenarios

Provides a quantum field theoretical explanation for non-singular cosmic origins

Bridges phenomenological models with fundamental quantum physics

Abstract

Emergent scenario of cosmic evolution is a topic of great interest in recent cosmology, especially because it describes a non-singular origin of the Universe unlike the Big-Bang models. This types of cosmic evolution pattern have already been established through the non-equilibrium thermodynamic prescription. But those models are phenomenological and requires physical interpretation from the perspective of quantum field theory. This work is an effort to search a quantum field theoretical reason to justify the emergent nature of the Universe and the nature of cosmic evolution at the early phase of the cosmic expansion.
