Power-law entropy-corrected holographic dark energy in Hořava-Lifshitz cosmology with Granda-Oliveros cut-off

Abstract

In this paper, we study the Power Law Entropy Corrected Holographic Dark Energy (PLECHDE) model in the framework of a non-flat Universe and of Hořava-Lifshitz cosmology with infrared cut-off given by recently proposed Granda-Oliveros cut-off, which contains one term proportional to the Hubble parameter squared H 2 and one term proportional to the first time derivative of the Hubble parameterḢ. Moreover, this cut-off is characterized by two constant parameters, α and β. For the two cases corresponding to noninteracting and interacting DE and Dark Matter (DM), we derive the evolutionary form of the energy density of DE Ω ′ D , the Equation of State (EoS) parameter of DE ω D and the deceleration parameter q. Using the parametrization of the EoS parameter ω D (z) = ω 0 + ω 1 z,we obtain the expressions of the two parameters ω 0 and ω 1 . We also study the statefinder parameters {r, s}, the snap and lerk cosmographic parameters and the squared speed of the sound v 2 s . We also calculate the values of the quantities we study for different values of the running parameter λ and for different set of values of α and β.

Holographic dark energy through Tsallis entropy

Holographic dark energy leads to interesting cosmological phenomenology [16][17][18][19][20][21][22][23][24][25][26][27] and it has been also extended through various ways [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47]. Additionally, holographic dark energy can be shown to be in agreement with observational data [48][49][50][51][52][53].…”

Mass varying neutrinos, symmetry breaking, and cosmic acceleration

“…This can be reexpressed as why in the early time, the dark energy density was negligible. The present proportion of dark sectors can be explained by considering the possible interaction of dark energy with other components [34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51]. Known physical properties of these components may give some clues to understand the behavior of dark energy.…”

Exploring Late‐Time Cosmic Acceleration with Eos Parameterizations in Horava‐Lifshitz Gravity via Baryon Acoustic Oscillations

“…[47,48] Despite many ambiguities regarding foundational and conceptual issues of HL gravity, [49,50] the different cosmological scenario has been examined by several authors. [51][52][53][54][55][56] In this paper, we will explore the mystery of cosmic acceleration by using a parameterized form of the DE equation of state (EoS) instead of relying on specific DE models. This way, we can avoid some problems with assuming a particular model, such as divergence issues and the possibility of misrepresenting the true nature of DE.…”
