Observational constraints of the modified cosmology through Barrow entropy [PDF]
European Physical Journal C: Particles and Fields, 2022 Taking into account a fractal structure for the black hole horizon, Barrow argued that the area law of entropy is modified due to quantum-gravitational effects (Barrow in Phys Lett B 808:135643, https://doi.org/10.1016/j.physletb.2020.135643 , 2020 ...

Barrow entropies in black hole thermodynamics
European Physical Journal C: Particles and FieldsWe study the thermodinamic features of static, spherically-symmetric Schwarzschild black holes adopting different types of Barrow entropy. Specifically, in addition to the standard Barrow entropy, we consider a logarithmic-corrected type of this entropy ...

Constraining barrow entropy-based cosmology with power-law inflation [PDF]
The European Physical Journal C, 2023 We study the inflationary era of the Universe in a modified cosmological scenario based on the gravity-thermodynamics conjecture with Barrow entropy instead of the usual Bekenstein–Hawking one.

Sign Switching Dark Energy from a Running Barrow Entropy [PDF]
Universe, 2022 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 S∝A1+δ/2, where 0⩽δ⩽1 measures the deviation from the standard area law (

Remote Sensing, 2015 Active layer thickness (ALT) is a critical parameter for monitoring the status of permafrost that is typically measured at specific locations using probing, in situ temperature sensors, or other ground-based observations.

Baryon asymmetry from Barrow entropy: theoretical predictions and observational constraints [PDF]
The European Physical Journal C, 2022 We investigate the generation of baryon asymmetry from the corrections brought about in the Friedman equations due to Barrow entropy. In particular, by applying the gravity-thermodynamics conjecture one obtains extra terms in the Friedmann equations that

Barrow holographic dark energy with Granda–Oliveros cutoff [PDF]
The European Physical Journal Plus, 2022 A study on the effects of implementing the Granda–Oliveros infrared cutoff in the recently introduced Barrow holographic dark energy model is presented, and its cosmological evolution is investigated.

Growth of perturbations in Tsallis and Barrow cosmology [PDF]
The European Physical Journal C, 2022 We report the effects of entropic corrections to the Friedmann equations on the growth of perturbations in the early stages of the universe. We consider two types of corrections to the area law of entropy, known as Tsallis and Barrow entropy. Using these

Barrow holographic dark energy in the Brans–Dicke cosmology [PDF]
The European Physical Journal Plus, 2022 We construct a holographic model for dark energy in the Brans–Dicke cosmology by using the holographic principle considering the Barrow entropy instead of the standard Bekenstein–Hawking one.

Modified cosmology through Barrow entropy [PDF]
Physical Review D, 2022 We investigate the cosmological consequences of the modified Friedmann equations when the entropy associated with the apparent horizon, given by Barrow entropy, $S\sim A^{1+\delta/2}$, where $0\leq\delta\leq1$, represents the amount of the quantum ...
