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 …

Analysis of a regular black hole in verlinde's gravity

AA Araújo Filho - Classical and Quantum Gravity, 2023 - iopscience.iop.org
This work focuses on the examination of a regular black hole within Verlinde's emergent
gravity, specifically investigating the Hayward-like (modified) solution. The study reveals the …

[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 …

Primordial gravitational waves in horizon cosmology and constraints on entropic parameters

SD Odintsov, S D'Onofrio, T Paul - Physical Review D, 2024 - APS
The hallmark of the four-parameter generalized entropy is that it can represent various
known entropies proposed so far for suitable limits of the parameters, and thus the four …

Critical gravity in four dimensions

H Lü, CN Pope - Physical Review Letters, 2011 - APS
We study four-dimensional gravity theories that are rendered renormalizable by the
inclusion of curvature-squared terms to the usual Einstein action with a cosmological …

[HTML][HTML] From the emergence of cosmic space to horizon thermodynamics in Barrow entropy-based Cosmology

GG Luciano - Physics Letters B, 2023 - Elsevier
Padmanabhan's paradigm states that the spatial expansion of our Universe can be
understood as the consequence of the emergence of space with the progress of cosmic …

Horizon entropy consistent with the FLRW equations for general modified theories of gravity and for all equations of state of the matter field

S Nojiri, SD Odintsov, T Paul, S SenGupta - Physical Review D, 2024 - APS
The question that continues to hinge the interrelation between cosmology and
thermodynamics is broadly described as—What is the form of horizon entropy that links the …

[HTML][HTML] Corrections to Friedmann equations inspired by Kaniadakis entropy

A Sheykhi - Physics Letters B, 2024 - Elsevier

Implications, consequences and interpretations of generalized entropy in the cosmological setups

H Moradpour - International Journal of Theoretical Physics, 2016 - Springer
Recently, it was argued (Tsallis and Cirto, Eur. Phys. J. C 73, 2487 2013) that the total
entropy of a gravitational system should be related to the volume of system instead of the …

Entropic corrections to Friedmann equations

A Sheykhi - Physical Review D—Particles, Fields, Gravitation, and …, 2010 - APS
Recently, Verlinde discussed that gravity can be understood as an entropic force caused by
changes in the information associated with the positions of material bodies. In Verlinde's …
