Constraining fractionality using some observational tests

H. Moradpour, S. Jalalzadeh, R. Jalalzadeh +1

Recently, a fractional version of the Schwarzschild-Tangherlini black hole with a fractal horizon has been introduced. Motivated by the key role of the Schwarzschild solution in gr…

Reduced Phase Space Quantization and Quantum Corrected Entropy of Schwarzschild-de Sitter Horizons

S. Jalalzadeh, H. Moradpour

This paper investigates the quantization of the Schwarzschild--de Sitter (SdS) black hole (BH) using the Misner--Sharp--Hernandez (MSH) mass as the internal energy in a reduced pha…

Fractional Schwarzschild-Tangherlini black hole with a fractal event horizon

S. Jalalzadeh, H. Moradpour, G. R. Jafari +1

We demonstrate that the implementation of the fractional and non-local Wheeler--DeWitt (WDW) equation within the context of Schwarzschild geometry leads to the emergence of a Schwa…

Fractional entropy of the Brown-Kuchař dust in fractional anti-de Sitter quantum gravity

P. F. da Silva Júnior, S. Jalalzadeh, H. Moradpour

This study derives the mass spectrum and entropy of the Brown-Kuchař dust in anti-de Sitter (AdS) spacetime using the fractional Wheeler-DeWitt (WDW) equation. The generalized frac…

Fractional Stars

H. Moradpour, S. Jalalzadeh, M. Javaherian

This study examines the possibility of starting the process of collapsing and forming stars from a fractional molecular cloud. Although the Verlinde's approach is employed to deriv…

Friedmann equations of the fractal apparent horizon

R. Jalalzadeh, S. Jalalzadeh, A. Sayahian Jahromi +1

From a fractal perspective, the entropy bound of gravitational systems undergoes changes. Furthermore, in the cosmological setting, the conservation law of a perfect fluid is also…

Modified cosmology from quantum deformed entropy

S. Jalalzadeh, H. Moradpour, P. V. Moniz

In Ref. [S. Jalalzadeh, Phys. Lett. B 829 (2022) 137058], Jalalzadeh established that the thermodynamical entropy of a quantum-deformed black hole with horizon area can be writ…

Some applications of the Shapiro time delay

A. Ghasemi Azar, H. Rezaei, H. Moradpour

Listening to echoes has long been a way to estimate distances, a technique whose backbone is the time delay. The gravitational field also creates a time delay, called Shapiro time…

On the thermodynamics of reconciling quantum and gravity

H. Moradpour, S. Jalalzadeh, Umesh Kumar Sharma

Is thermodynamics consistent with the quantum gravity reconciliation hypothesis [A. G. Cohen et al. Phys. Rev. Lett. 82, 4971 (1999)], which establishes holographic dark energy mod…
