Decaying Holographic Dark Energy and Emergence of Friedmann Universe

TL;DR

This paper explores a model where decaying holographic dark energy leads to the emergence of a Friedmann universe from an initial de Sitter phase, consistent with Einstein's equations.

Contribution

It introduces a framework for a universe evolving from a de Sitter phase to a Friedmann universe via decaying holographic dark energy and matter creation.

Findings

Universe can evolve from de Sitter to Friedmann phase

Decaying holographic dark energy is consistent with Einstein's equations

Matter creation from dark energy is theoretically modeled

Abstract

A universe started in almost de Sitter phase with time varying holographic dark energy corresponding to a time varying cosmological term is considered. The time varying cosmological dark energy and the created matter are consistent with the Einstein's equation. The general conservation law for decaying dark energy and created matter is stated. By asuming that the initial matter were crated in relativistic form, we have analysed the possibility of evolving the universe from de Sitter phase to Friedmann universe.
