A gracious exit from the matter-dominated phase in a quantum cosmic phantom model

TL;DR

This paper proposes a quantum cosmic phantom model where quantum potentials cause matter particles to effectively vanish at matter-radiation equality, enabling a transition from matter dominance to accelerated expansion consistent with recent observational data.

Contribution

It introduces a novel quantum cosmological model with quantum potentials that modify matter particle masses, allowing a matter-dominated phase followed by acceleration, aligning with Planck data.

Findings

Quantum potentials cause matter particle masses to vanish at matter-radiation equality.

The model permits a matter dominance phase followed by cosmic acceleration.

Compatibility with recent Planck observational constraints.

Abstract

The most recent observational constraints coming from Planck, when combined with other cosmological data, provide evidence for a phantom scenario. In this work we consider a quantum cosmic phantom model where both the matter particles and scalar field are associated with quantum potentials which make the effective mass associated with the matter particles to vanish at the time of matter-radiation equality, resulting in a cosmic system where a matter dominance phase followed by an accelerating expansion is allowed.
