Kaniadakis agegraphic dark energy

چکیده

In this manuscript, we present a novel dark energy scenario based on Kaniadakis entropy, which is generalization of Boltzmann–Gibbs entropy that arises from relativistic statistical theory and characterized by parameter K quantifies the deviations standard expressions, use age Universe as infrared cutoff. The cosmological characteristics proposed model, well evolution cosmos filled with pressure-free matter ensuing candidates, are investigated. interaction non-interaction among two sectors will also be considered. differential equation for density parameter, including expression state deceleration parameters, derived. analysis clearly shows universe to transit decelerated accelerated phase around z≈0.6. most recent 30 H(z) data samples 580 Union 2.1 SNIa set were used limit theoretical results. squared sound speed plotted against redshift z check stability behavior model both cases.

Interacting Agegraphic Dark Energy

A new dark energy model, named as “agegraphic dark energy”, has been proposed by one of us (R. G. Cai) in arXiv:0707.4049, based on the Károlyházy uncertainty relation, which arises from the quantum mechanics together with general relativity. In this note, we extend the original agegraphic dark energy model by including the interaction between the agegraphic dark energy and the pressureless (da...

A Note on Agegraphic Dark Energy

Recently a new model of dynamical dark energy, or time-varying Λ, was proposed by Cai [arXiv:0707.4049] by relating the energy density of quantum fluctuations in a Minkowski spacetime, namely ρq ≡ 3n2m2P /t, where n ∼ O(1) and t is the cosmic time, to the present day dark energy density. In this note, we show that the model can be adjusted to the present values of dark energy density parameter ...

Interacting new agegraphic dark energy model and generalized second law of thermodynamics in non-flat universe

We consider the interacting new agegraphic dark energy model to investigate the validity of the generalized second law of thermodynamics in non-flat universe enclosed by the apparent horizon. We show that for this model in presence of interaction with the cold dark matter, the equation of state parameter can cross the phantom divide. We also present that for the selected model under thermal equ...

Dark Matter and Dark Energy

I briefly review our current understanding of dark matter and dark energy. The first part of this paper focusses on issues pertaining to dark matter including observational evidence for its existence, current constraints and the ‘abundance of substructure’ and ‘cuspy core’ issues which arise in CDM. I also briefly describe MOND. The second part of this review focusses on dark energy. In this pa...

Dark energy with dark spinors

Ever since the first observations that we are living in an accelerating universe, it has been asked what dark energy is. There are various explanations all of which with have various draw backs or inconsistencies. Here we show that using a dark spinor field it is possible to have an equation of state that crosses the phantom divide, becoming a dark phantom spinor which evolves into dark energy....
