Generalized particle dynamics in anti de Sitter spaces: A source for dark energy

TL;DR

This paper introduces a new model based on generalized particle dynamics in anti de Sitter spaces that explains the late-time acceleration of the universe and produces an effective dark energy with phantom-like behavior.

Contribution

It develops a novel framework embedding the FRW universe in a higher-dimensional space using generalized particle dynamics, explaining dark energy phenomena.

Findings

The model reproduces observed cosmological parameters.

It predicts a phantom-like dark energy equation of state.

The framework links particle dynamics to cosmic acceleration.

Abstract

We consider the generalized particle dynamics, proposed by us, in brane world formalisms for an asymptotically anti de Sitter background. The present framework results in a new model that accounts for the late acceleration of the universe. An effective Dark Energy equation of state, exhibiting a phantom like behaviour, is generated. The model is derived by embedding the physical FRW universe in a $(4+1)$-dimensional effective space-time, induced by the generalized particle dynamics. We corroborate our results with present day observed cosmological parameters.
