New type scalar fields for cosmic acceleration

TL;DR

This paper introduces a novel scalar field model that can mimic dark energy and drive cosmic acceleration, offering potential insights into the cosmological constant problem.

Contribution

It proposes a new type of scalar field configuration that effectively acts as a cosmological constant, contributing to dark energy modeling.

Findings

Scalar field can induce cosmic acceleration

Model provides an alternative explanation for dark energy

Discussion on implications for the cosmological constant problem

Abstract

We present a model where a non-conventional scalar field may act like dark energy leading to cosmic acceleration. The latter is driven by an appropriate field configuration, which result in an effective cosmological constant. The potential role of such a scalar in the cosmological constant problem is also discussed.
