Quantisation of the holographic Ricci dark energy model

TL;DR

This paper performs a quantum analysis of the Holographic Ricci Dark Energy model, demonstrating that quantum effects can prevent both future cosmic singularities and the initial Big Bang.

Contribution

It introduces a quantum cosmological framework for the HRDE model, showing how quantum effects can resolve classical singularities.

Findings

Quantum effects prevent future singularities in HRDE

Quantum cosmology avoids the initial Big Bang singularity

The model suggests a non-singular cosmic evolution

Abstract

While general relativity is an extremely robust theory to describe the gravitational interaction in our Universe, it is expected to fail close to singularities like the cosmological ones. On the other hand, it is well known that some dark energy models might induce future singularities; this can be the case for example within the setup of the Holographic Ricci Dark Energy model (HRDE). On this work, we perform a cosmological quantisation of the HRDE model and obtain under which conditions a cosmic doomsday can be avoided within the quantum realm. We show as well that this quantum model not only avoid future singularities but also the past Big Bang.
