Pathology of the Unified Dark Sectors in Modified General Relativity
Mohsen Khodadi
This paper presents a comprehensive stability analysis of the black hole solution within Modified General Relativity (MGR), a theory proposing a unified geometric description of da…
Einstein-Æther Gravity in the light of Event Horizon Telescope Observations of M87*
Mohsen Khodadi, Emmanuel N. Saridakis
We investigate Einstein-Æther gravity in light of the recent Event Horizon Telescope (EHT) observations of the M87*. The shape and size of the observed black hole shadow contains i…
On the viability of Planck scale cosmology with quartessence
Mohsen Khodadi, Kourosh Nozari, Fazlollah Hajkarim
In this paper, using a qualitative theory of dynamical systems, we study the stability of a unified dark matter-dark energy framework known as quartessence Chaplygin model (QCM) wi…
Non-singular model universe from a perfect fluid scalar-metric cosmology
Mohsen Khodadi, Kourosh Nozari
To seek for a singularity free model universe from a perfect fluid scalar-metric cosmology, we work in the "\emph{Emergent Cosmology}" (EC) paradigm which is a non-singular alterna…
Probing Planck Scale Spacetime By Cavity Opto-Atomic Rb Interferometry
M. Khodadi, K. Nozari, A. Bhat +1
The project of \emph{"quantum spacetime phenomenology"} focuses on searching pragmatically for the Planck scale quantum features of spacetime. Among these features is the existence…
A new bound on polymer quantization via an opto-mechanical setup
M. Khodadi, K. Nozari, S. Dey +2
The existence of a minimal measurable length as a characteristic length in the Planck scale is one of the main features of quantum gravity and has been widely explored in the conte…
Some Astrophysical Aspects of a Schwarzschild Geometry Equipped with a Minimal Measurable Length
Mohsen Khodadi, Kourosh Nozari, Anahita Hajizadeh
By considering a deformation of the Schwarzschild metric in the presence of a minimal measurable length which still respects the equivalence principle, we study corrections to the…
Emergent universe in theories with natural UV cutoffs
Mohsen Khodadi, Kourosh Nozari, Emmanuel N. Saridakis
We investigate the realization of the emergent universe scenario in theories with natural UV cutoffs, namely a minimum length and a maximum momentum, quantified by a new deformatio…
Some Features of Scattering Problem in a -Deformed Minkowski Spacetime
Mohsen Khodadi, Kourosh Nozari
The doubly special relativity (DSR) theories are suggested in order to incorporate an observer-independent length scale in special theory of relativity. The Magueijo-Smolin proposa…
Classical and quantum dynamics of a perfect fluid scalar-energy dependent metric cosmology
M. Khodadi, K. Nozari, B. Vakili
Inspired from the idea of minimally coupling of a real scalar field to geometry, we investigate the classical and quantum models of a flat energy-dependent FRW cosmology coupled to…
More on the initial singularity problem in gravity's rainbow cosmology
M. Khodadi, K. Nozari, H. R. Sepangi
Using a one-dimensional minisuperspace model with a dimensionless ratio , we study the initial singularity problem at the quantum level for the closed rainbow cos…
Bounds on quantum gravity parameter from the NJL effective model of QCD
K. Nozari, M. Khodadi, M. A. Gorji
Existence of a minimal measurable length, as an effective cutoff in the ultraviolet regime, is a common feature of all approaches to the quantum gravity proposal. It is widely beli…
On the Stability of Einstein Static Universe in Doubly General Relativity Scenario
M. Khodadi, Y. Heydarzade, K. Nozari +1
By presenting a relation between average energy of the ensemble of probe photons and energy density of the Universe, in the context of {\it gravity's rainbow} or {\it doubly genera…
Deformed Horava-Lifshitz Cosmology and Stability of Einstein Static Universe
Y. Heydarzade, M. Khodadi, F. Darabi
Stability of the Einstein static universe versus the linear scalar, vector and tensor perturbations is investigated in the context of deformed Hořava-Lifshitz cosmology inspired by…
