Unified cosmic history in modified gravity: from F (R) theory to Lorentz non-invariant models
The classical generalization of general relativity is considered as the gravitational alternative
for a unified description of the early-time inflation with late-time cosmic acceleration. The …

Late-time cosmology in a (phantom) scalar-tensor theory: dark energy and the cosmic speed-up
We consider 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 …

The phantom menaced: Constraints on low-energy effective ghosts
JM Cline, S Jeon, GD Moore - Physical Review D, 2004 - APS
It has been suggested that a scalar field with negative kinetic energy, or “ghost,” could be the
source of the observed late-time cosmological acceleration. Naively, such theories should …

Final state and thermodynamics of a dark energy universe
As it follows from the classical analysis, the typical final state of a dark energy universe
where a dominant energy condition is violated is a finite-time, sudden future singularity (a …

Reconstruction of gravity: Rip cosmology, finite-time future singularities, <?format ?>and thermodynamics
We demonstrate that there appear finite-time future singularities in f (T) gravity with T being
the torsion scalar. We reconstruct a model of f (T) gravity with realizing the finite-time future …
