Review on Dark Energy ModelsReview on Dark Energy ModelsBased on quantum mechanics and general relativity, Karolyhazy proposed a generalization to the well-known Heisenberg uncertainty relation in which the energy density of quantum fluctuations of space-time plays a crucial role. Later on, various ...

The Lagrangian (29) leads to a unified dark energy model in which the effects of dark energy are induced by the presence of dark matter. Analogous results can be found as one adds Lagrange multipliers to the scenario with a standard kinetic term [27, 28]. However, this case guarantees tha...
A review on spatially flat D-dimensional Friedmann-Robertson-Walker (FRW) model of the universe has been performed. Some standard parameterizations of the equation of state parameter of the dark energy models are proposed and the possibilities of finite time future singularities are investigated. It ...
Astrophysical observations reveal that in the present epoch the DE shares almost 69% of the total energy in the Universe while visible and dark matter together make up to 31% [1]. Various models explaining the origin of DE have been proposed in the literature, for a brief review see e.g...
of thecurrently standard model of cosmology(the SMoC, the other two pillars being inflation and dark energy). Dark matter leads to the growth of structure such that galaxy-like objects can exist in the model and to the phenomenon of these model galaxies merging rather than just flying past ea...

67]. In the quintessence model of dark energy, the speed of sound is unity. For this case, the perturbation in the scalar field is negligible. Consequently, this corresponds to the homogeneity of the dark energy. In the non-canonical k-essence scenario, the sound speed of dark energy is ...
The nine free parameters of the f (R, G, T ) dark energy model, namely H0, m0, r0, β1, β2, β3, α1, α2, α3 , along with the present-day value of the Hubble function H0, are constrained using the stan- dard Bayesian technique, likelihood function approach, and Markov ...
