Embedding of FRW Cosmology in DGP Scenario with a Non-Minimally Coupled Scalar Field on the Brane

TL;DR

This paper develops a braneworld cosmological model inspired by DGP theory, incorporating a non-minimally coupled scalar field, which reproduces standard Friedmann cosmology and connects to dark energy concepts.

Contribution

It introduces a novel DGP-inspired model with a non-minimally coupled scalar field on the brane that embeds standard Friedmann cosmology.

Findings

Standard Friedmann equations are recovered in the model.

The framework relates to dark energy formalism.

The model provides a new approach to braneworld cosmology.

Abstract

We construct a DGP inspired braneworld scenario where a scalar field non-minimally coupled to the induced Ricci curvature is present on the brane. We show that this model allows for an embedding of the standard Friedmann cosmology in the sense that the cosmological evolution of the background metric on the brane can be described by the standard Friedmann equation. The relation between our framework and the dark-energy formalism is explored.
