A Real Scalar Field Unifying the Early Inflation and the Late Accelerating Expansion of the Universe through a Quadratic Equation of State: The Vacuumon

Abstract: In a previous paper we introduced a cosmological model describing the early inflation, the intermediate decelerated expansion, and the late accelerating expansion of the universe in terms of a single barotropic fluid characterized by a quadratic equation of state. We obtained a scalar field representation of this fluid and determined the potential V(ϕ) connecting the inflaton potential in the early universe to the quintessence potential in the late universe. This scalar field has later been called the `vacuumo… Show more

“…Mixed models of type I of the form of Equations ( 413)-(415) have been introduced and studied in cosmology in Refs. [97][98][99][166][167][168][169][170]. In particular, the equations of state (414) and (415) describe the early inflation, the intermediate decelerating expansion, and the late accelerating expansion of the universe in a unified manner [168,170].…”

“…This SF is respectively called inflaton or quintessence. A single SF called vacuumon may even drive the whole evolution of the universe from its early inflation to its late accelerating expansion [170]. Recently, using the general formalism developed in this paper, we have specifically studied polytropic and logotropic equations of state of type III in Refs.…”
