The new form of the equation of state for dark energy fluid and accelerating universe
TLDR
In this article, the authors proposed to generalize the dark energy equation of state (EoS) by introducing the relaxation equation for pressure which is equivalent to consideration of the inhomogeneous EoS cosmic fluid which often appears as the effective model from strings/brane-worlds.About:

Black Holes, Cosmological Solutions, Future Singularities, and Their Thermodynamical Properties in Modified Gravity Theories
TL;DR: In this paper, the authors focus on the properties of modified gravity theories, in particular on black-hole solutions and its comparison with those solutions in General Relativity, and on Friedmann-Lemaitre-Robertson-Walker metrics.

Tsallis holographic dark energy
TL;DR: In this paper, a new holographic dark energy (HDE) model was proposed for the Friedmann-Robertson-Walker (FRW) universe in which there is no interaction between the cosmos sectors.

Cosmological constant—the weight of the vacuum
TL;DR: A review of cosmological constants can be found in this paper, where the authors discuss several aspects of the Cosmological Constant problem from both cosmology and theoretical perspectives.

Coupled Quintessence
TL;DR: The cosmological consequences of such a coupled quintessence (CQ) model, assuming an exponential potential and a linear coupling, were investigated in this article, where the authors evaluated the density perturbations on the cosmic microwave background and on the galaxy distribution at the present and derived bounds on the coupling constant.

Properties of singularities in the (phantom) dark energy universe
TL;DR: In this paper, the properties of future singularities are investigated in the universe dominated by dark energy including the phantom-type fluid. And the authors classify the finite-time singularities into four classes and explicitly present the models which give rise to these singularities by assuming the form of the equation of state of dark energy.

Late-time cosmology in (phantom) scalar-tensor theory: dark energy and the cosmic speed-up
TL;DR: In this article, the authors considered late-time cosmology in a (phantom) scalar-tensor theory with an exponential potential, as a dark energy model with equation of state parameter close to -1 (a bit above or below this value).
Journal ArticleDOI
Quantum de Sitter cosmology and phantom matter
TL;DR: In this article, the authors considered the de Sitter universe and Nariai universe induced by quantum CFT with classical phantom matter and perfect fluid and showed that it is easier to achieve the acceleration of the scale factor preserving the energy conditions in such unified model.
