Modified gravity theories on a nutshell: Inflation, bounce and late-time evolution

S Nojiri, SD Odintsov, VK Oikonomou - Physics Reports, 2017 - Elsevier
We systematically review some standard issues and also the latest developments of
modified gravity in cosmology, emphasizing on inflation, bouncing cosmology and late-time …

Unified cosmic history in modified gravity: from F (R) theory to Lorentz non-invariant models

S Nojiri, SD Odintsov - Physics Reports, 2011 - Elsevier
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 …

Dynamics of dark energy

EJ Copeland, M Sami, S Tsujikawa - International Journal of Modern …, 2006 - World Scientific
We review in detail a number of approaches that have been adopted to try and explain the
remarkable observation of our accelerating universe. In particular we discuss the arguments …

Dark energy cosmology: the equivalent description via different theoretical models and cosmography tests

K Bamba, S Capozziello, S Nojiri… - Astrophysics and Space …, 2012 - Springer
We review different dark energy cosmologies. In particular, we present the Λ CDM
cosmology, Little Rip and Pseudo-Rip universes, the phantom and quintessence …

Properties of singularities in the (phantom) dark energy universe

S Nojiri, SD Odintsov, S Tsujikawa - Physical Review D—Particles, Fields …, 2005 - APS
The properties of future singularities are investigated in the universe dominated by dark
energy including the phantom-type fluid. We classify the finite-time singularities into four …

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

E Elizalde, S Nojiri, SD Odintsov - Physical Review D, 2004 - APS
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

S Nojiri, SD Odintsov - Physical Review D—Particles, Fields, Gravitation, and …, 2004 - APS
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

K Bamba, R Myrzakulov, S Nojiri, SD Odintsov - Physical Review D—Particles …, 2012 - APS
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 …

Black holes, cosmological solutions, future singularities, and their thermodynamical properties in modified gravity theories

A de la Cruz-Dombriz, D Sáez-Gómez - Entropy, 2012 - mdpi.com
Along this review, we focus on the study of several properties of modified gravity theories, in
particular on black-hole solutions and its comparison with those solutions in General …
