Holographic dark energy

S Wang, Y Wang, M Li - Physics reports, 2017 - Elsevier
We review the paradigm of holographic dark energy (HDE), which arises from a theoretical
attempt of applying the holographic principle (HP) to the dark energy (DE) problem. Making …

Barrow entropy corrections to Friedmann equations

A Sheykhi - Physical Review D, 2021 - APS
Recently, Barrow argued that quantum-gravitational effects may introduce intricate, fractal
features on the black hole horizon [JD Barrow,, The area of a rough black hole, Phys. Lett. B …

Thermodynamic behavior of the Friedmann equation at the apparent horizon<? format?> of the FRW universe

M Akbar, RG Cai - Physical Review D—Particles, Fields, Gravitation, and …, 2007 - APS
It is shown that the differential form of Friedmann equation of a FRW universe can be
rewritten as the first law of thermodynamics d E= T d S+ W d V at apparent horizon, where …

Thermodynamic parametrization of dark energy

S Capozziello, R D'Agostino, O Luongo - Physics of the Dark Universe, 2022 - Elsevier
We propose a new parametrization of dark energy motivated by thermodynamics. To this
aim, we consider Padé polynomials to reconstruct the form of deceleration parameter …

[HTML][HTML] Modified Friedmann equations from Tsallis entropy

A Sheykhi - Physics Letters B, 2018 - Elsevier
It was shown by Tsallis and Cirto that thermodynamical entropy of a gravitational system
such as black hole must be generalized to the non-additive entropy, which is given by S h= γ …

The generalized second law of thermodynamics with Barrow entropy

EN Saridakis, S Basilakos - The European Physical Journal C, 2021 - Springer
We investigate the validity of the generalized second law of thermodynamics, applying
Barrow entropy for the horizon entropy. The former arises from the fact that the black-hole …

Dynamics of an interacting Barrow holographic dark energy model and its thermodynamic implications

AA Mamon, A Paliathanasis, S Saha - The European Physical Journal …, 2021 - Springer
In this paper, using Barrow entropy, we propose an interacting model of Barrow holographic
dark energy (BHDE). In particular, we study the evolution of a spatially flat FLRW universe …

Sign switching dark energy from a running barrow entropy

S Di Gennaro, YC Ong - Universe, 2022 - mdpi.com
Barrow proposed that the area law of the entropy associated with a horizon might receive a
“fractal correction” due to quantum gravitational effects—in place of S∝ A, we have instead …

Thermodynamics of dark energy interacting with dark matter and radiation

M Jamil, EN Saridakis, MR Setare - Physical Review D—Particles, Fields …, 2010 - APS
We investigate the validity of the generalized second law of thermodynamics, in the
cosmological scenario where dark energy interacts with both dark matter and radiation …

Modified cosmology through Barrow entropy

A Sheykhi - Physical Review D, 2023 - APS
We investigate the cosmological consequences of the modified Friedmann equations when
the entropy associated with the apparent horizon, given by Barrow entropy, S∼ A 1+ δ/2 …
