Journal ArticleDOI
Crossing the w = - 1 barrier in the D3-brane dark energy model
TL;DR: In this article, the authors consider the universe as a slowly decaying D3-brane and explore a possibility for the universe to cross the cosmological constant barrier for the dark energy state parameter.
Journal ArticleDOI
Exactly Solvable SFT Inspired Phantom Model
TL;DR: In this article, an exact solution to the Friedmann equations with a string inspired phantom scalar matter field is constructed and the absence of the Big Rip singularity is shown explicitly; the model is stable with respect to small fluctuations of the initial conditions and special deviations of the form of the potential.
Journal ArticleDOI
Bouncing and Accelerating Solutions in Nonlocal Stringy Models
TL;DR: In this paper, a general class of cosmological models driven by a non-local scalar field inspired by string field theories is studied and a distinguished feature of these models is a crossing of the phantom divide.
Journal ArticleDOI
De Sitter universe in nonlocal gravity
TL;DR: In this paper, a nonlocal gravity model, which does not assume the existence of a new dimensional parameter in the action and includes a function $f(\Box^{-1} R), with $\Box$ the d'Alembertian operator, is considered.
Journal ArticleDOI
Dynamics in nonlocal linear models in the Friedmann-Robertson-Walker metric
TL;DR: In this paper, a general class of cosmological models driven by a nonlocal scalar field inspired by the string field theory is studied, and an exact special solution of the nonlocal Friedmann equations is found.
