Emergent Universe with Exotic Matter in Brane World Scenario

TL;DR

This paper explores the emergent universe scenario within brane world models incorporating exotic matter like phantom and tachyonic fields, revealing conditions under which such scenarios are feasible across different universe geometries.

Contribution

It demonstrates the possibility of emergent universe scenarios with exotic matter in brane world models, extending previous work to include phantom and tachyonic fields across various geometries.

Findings

Emergent scenario possible for tachyonic matter in all universe models with potential restrictions.

Normal scalar field emergent scenario only in closed universe, aligning with previous studies.

Phantom field allows emergent scenario in closed, open, and flat universes with potential restrictions.

Abstract

In this work, we have examined the emergent scenario in brane world model for phantom and tachyonic matter. For tachyonic matter field we have obtained emergent scenario is possible for closed, open and at model of the universe with some restriction of potential. For normal scalar field the emergent scenario is possible only for closed model and the result is identical with the work of Ellis et al [2], but for phantom field the emergent scenario is possible for closed, open and at model of the universe with some restriction of potential.
