Abstract We use Big Bang Nucleosynthesis (BBN) data in order to impose constraints on the
exponent of Barrow entropy. The latter is an extended entropy relation arising from the …

We construct Barrow holographic dark energy in the case of nonflat universe. In particular,
considering closed and open spatial geometry we extract the differential equations that …

In this work, we propose a non-interacting model of Barrow holographic dark energy (BHDE)
using Barrow entropy in a spatially flat FLRW Universe considering the IR cutoff as the …

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 …

We use data from M87* central black hole shadow, as well as from the S2 star observations,
in order to extract constraints on Barrow entropy. The latter is a modified entropy arising from …

In this work, we propose a new dark energy (DE) model by applying the Barrow entropy and
the holographic principle, with a time scale as IR cut-off. Analyzing the conformal time as …

We study the phase transition and thermodynamic geometries of a charged AdS black hole
with a global monopole. For this purpose, we develop the thermodynamic quantities such as …

The current study takes into account the evolution of a fractal universe with holographic dark
energy through Barrow entropy and dark matter, ie without pressure, which interact with one …

Barrow proposed that the area law of the horizon entropy might receive a “fractal
correction”\(S\propto A^{1+\Delta/2}\) due to quantum gravitational effects …

One of the challenges of today's theoretical physics is to fully understand the connection
between a geometrical object like area and a thermostatistical one like entropy, since we …
