Born-Infeld Quantum Condensate as Dark Energy in the Universe

TL;DR

This paper explores how quantum effects in Born-Infeld matter could lead to a condensate that acts as dark energy, behaving like a cosmological constant under certain conditions.

Contribution

It demonstrates that quantum condensates of Born-Infeld matter can serve as an effective dark energy component in the universe, under specific quantum dominance conditions.

Findings

Quantum condensate cannot act as phantom matter with positive energy density.

Under quantum dominance, the condensate behaves as an effective cosmological constant.

Abstract

Some cosmological implications of ultraviolet quantum effects leading to a condensation of Born-Infeld matter are considered. It is shown that under very general conditions the quantum condensate can not act as phantom matter if its energy density is positive. On the other hand, it behaves as an effective cosmological constant in the limit where quantum induced contributions to the energy-momentum tensor dominate over the classical effects.
