Thermodynamic formulation of Cotton gravity in the Codazzi parametrization
Shayesteh Ghaffari, Giuseppe Gaetano Luciano, Carlo Alberto Mantica
We develop a thermodynamic formulation of Cotton gravity in the Codazzi parametrization, providing a general framework in which the gravitational dynamics can be interpreted in ter…
Gravitational Collapse of an Inhomogeneous Fluid in Rastall Theory
Akbar Jahan, Naser Sadeghnezhad, Amir Hadi Ziaie
We study spherically symmetric gravitational collapse of an inhomogeneous fluid with anisotropic energy momentum tensor (EMT) in Rastall gravity. Considering a linear equation of s…
Trace anomaly contributions to semi-classical wormhole geometries
Mohammad Reza Mehdizadeh, Amir Hadi Ziaie, Francisco S. N. Lobo
We investigate wormhole solutions within the framework of the semi-classical Einstein equations in the presence of the conformal anomaly (or trace anomaly). These solutions are sou…
Singularity Avoidance in Gravitational Collapse of an Inhomogeneous Fluid in Rastall Gravity
Akbar Jahan, Halime Miraghaei, Shayesteh Ghaffari +1
Various types of inhomogeneous collapse models in general relativity (GR) lead to the formation of spacetime singularities either visible or hidden by a spacetime horizon. Our aim…
Black Hole Thermodynamics in Harada's inspired theory of gravity: Stability, Phase Structure and Geometrothermodynamics
S. Ghaffari, G. G. Luciano
In this paper, we investigate the thermodynamic properties of spherically symmetric, static black hole solutions within the framework of Conformal Killing Gravity (CKG). This is a…
H0 tension in Tsallis and Renyi statistics

Motivated by recent attempts to study the implications of Tsallis and Renyi statistics in gravitational, cosmological, and astrophysical systems, the possible relationships between…
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…
Wormhole solutions in generalized Rastall gravity
Naser Sadeghnezhad
In the present work, we seek for static spherically symmetric solutions representing wormhole configurations in generalized Rastall gravity (GRG). In this theory, a varying couplin…
Casimir Wormholes in Brans-Dicke Theory
Amir Hadi Ziaie, Mohammad Reza Mehdizadeh
In recent years there has been a growing interest in the field of wormhole physics in the presence of the Casimir effect. As this effect provides negative energy density, it can be…
Novel Casimir wormholes in Einstein gravity
Mohammad Reza Mehdizadeh, Amir Hadi Ziaie
In the context of General Relativity (GR), violation of the null energy condition (NEC) is necessary for existence of static spherically symmetric wormhole solutions. Also, it is a…
Late time cosmological solutions in gravity in a viscous Universe
Hamid Shabani, Norman Cruz, Amir Hadi Ziaie
Considering the condition on conservation of energy momentum tensor (EMT), we study late time cosmological solutions in the context of gravity (where and …
Gravitational Collapse without Singularity Formation in Brans-Dicke Theory
A. H. Ziaie, H. Shabani, H. Moradpour
In the present work we study collapse process of a homogeneous and isotropic fluid in Brans-Dicke ({BD}) theory with non-vanishing spacetime torsion. In this theory, torsion can be…
Modified cosmology from quantum deformed entropy

A. Sheykhi, S. Ghaffari
We revisit agegraphic dark energy (ADE) model when the entropy associated with the apparent horizon is in the form of Barrow entropy, , where indicat…
