TL;DR
This paper surveys a string field theory-based nonlocal model of dark energy that predicts an equation of state parameter less than -1, discussing recent progress, open problems, and theoretical issues in cosmology applications.
Contribution
It introduces and reviews a novel nonlocal string field theory model of dark energy with w<-1, highlighting its potential and challenges in cosmological contexts.
Findings
Model predicts w<-1 for dark energy.
Summarizes recent developments in nonlocal SFT models.
Identifies open problems and theoretical issues.
Abstract
A string field theory(SFT) nonlocal model of the cosmological dark energy providing w<-1 is briefly surveyed. We summarize recent developments and open problems, as well as point out some theoretical issues related with others applications of the SFT nonlocal models in cosmology, in particular, in inflation and cosmological singularity.
