Observational Constraints on Emergent Fractional Fractal Cosmology
Raheleh Jalalzadeh, Hooman Moradpour, Shahram Jalalzadeh
We constrain the Emergent Fractional Fractal (EFF) cosmological model through a joint likelihood analysis of recent cosmological observations at the background and perturbation lev…
-Deformed Quantum Mechanics and the Thermodynamics of Black Hole/White Hole Spectral pair
S. Jalalzadeh, R. Jalalzadeh, H. Moradpour
In this work, we investigate the thermodynamics of Schwarzschild black and white holes within a -deformed Wheeler--DeWitt framework. By introducing a -deformed Heisenberg--We…
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…
Quantum corrected thermodynamics and horizon quantization of the Reissner--Nordström black hole
S. Jalalzadeh, H. Moradpour
In this letter, we develop a unified semiclassical framework for the thermodynamics and quantization of the Reissner--Nordström (RN) black hole (BH) based on the Misner--Sharp--Her…
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…
Minimal length: A source of quantum non-locality
H. Moradpour, S. Jalalzadeh
The narrow and subtle difference between the Hilbert spaces of operators corresponding to the canonical momentum and the generalized momentum that includes minimal length effects i…
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…
Cosmological Singularities in Brane Gravity
R. Jalalzadeh, S. Jalalzadeh, Y. Heydarzade
We present a comprehensive study of cosmological singularities within the framework of Covariant Extrinsic Gravity (CEG), addressing both the initial Big Bang singularity and poten…
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…
Observational constraints on FLRW, Bianchi type I and V brane models
R. Jalalzadeh, S. Jalalzadeh, B. Malekolkalami +1
This study explores the compatibility of Covariant Extrinsic Gravity (CEG) with current cosmological observations. We employ the chi-square statistic and Markov Chain Monte Carlo (…
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…
Estimated Age of the Universe in Fractional Cosmology
Emanuel Wallison de Oliveira Costa, Raheleh Jalalzadeh, Pedro Felix da Silva Júnior +2
Our proposed cosmological framework, which is based on fractional quantum cosmology, aims to address the issue of synchronicity in the age of the universe. To achieve this, we have…
Emergence of fractal cosmic space from fractional quantum gravity
P. F. da Silva Junior, E. W. de Oliveira Costa, S. Jalalzadeh
Based on Padmanabhan's theory, the spatial expansion of the Universe can be explained by the emergence of space as cosmic time progresses. To further explore this idea, we have dev…

S. M. M. Rasouli, E. W. Oliveira Costa, P. V. Moniz +1
The Wheeler--DeWitt equation for a flat and compact Friedmann--Lemaître--Robertson--Walker cosmology at the pre-inflation epoch is studied in the contexts of the standard and fract…
