Emergent Universe in f(Q) gravity theories
Hamid Shabani, Avik De, Tee-How Loo
One resolution of the ancient cosmic singularity, i.e., the Big Bang Singularity (BBS), is to assume an inflationary stage preceded by a long enough static state in which the unive…
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

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…
Thermodynamic schemes of charged BTZ-like black holes in arbitrary dimensions

We investigate thermodynamic schemes of charged BTZ-like black holes in arbitrary dimensions, namely higher-dimensional charged black holes in which the electromagnetic sector exhi…
A non-singular bouncing cosmology in gravity
J. K. Singh, Shaily, Akanksha Singh +2
We investigate a bounce realization in the framework of higher order curvature in modified theory of gravity. We perform a detailed analysis of the cosmological paramete…
Phase-space analysis of a novel cosmological model in theory
Hamid Shabani, Avik De, Tee-How Loo
The vanishing affine connections have been used solely while adopting the modified gravity theory to the cosmology. Consequently, researchers could not get beyond what is al…
Chiral Nonet Mixing in Scattering
Amir H. Fariborz, Soodeh Zarepour, Esmaiel Pourjafarabadi +1
The generalized linear sigma model for mixing among two- and four-quark components of scalar (and psedudosclar) mesons below and above 1 GeV is applied to the channel in which…
Heavy quarks structure functions and at the NLO approximation
S. Zarrin, S. Dadfar
We provide compact formulas for the heavy quarks structure functions and , with and , in interaction…
Einstein Static Universe and its Stability in Generalized Rastall Gravity
Hamid Shabani, Amir Hadi Ziaie, Hooman Moradpour
The Einstein static (ES) state is a good candidate for describing the very early universe in terms of a regular cosmological model in which the Big Bang singularity is avoided. In…
The galaxy rotation curves in the modified gravity formalism
H. Shabani, P. H. R. S. Moraes
Astronomical data have shown that the galaxy rotation curves are mostly flat in the far distance of the galactic cores, which reveals the insufficiency of our knowledges about how…
A dynamical system representation of generalized Rastall gravity
Hamid Shabani, Hooman Moradpour, Amir Hadi Ziaie
In this work we study the phase-space analysis of generalized Rastall gravity (GRG) which has recently been introduced as a modification to the original version of Rastall gravity…
Nonlinear corrections to the single differential cross section for neutral current e-p scattering at the NLO approximation
S. Zarrin, S. Dadfar
We present the effects of nonlinear corrections to the single differential cross section dσ/dQ^2 and the reduced cross section σ_r (x,Q^2) for the neutral current (NC) e-p scatteri…
Scattering of the asymmetric kinks from a -symmetric perturbation: Creation of multiple pairs of kink-antikink from phonons
Danial Saadatmand, Aliakbar Moradi Marjaneh
Interaction of asymmetric kinks with a spatially localized -symmetric perturbation is investigated numerically. It has been shown that when the kink (antikink)…
Self-energy problem, vacuum polarization, and dual symmetry in Born-Infeld-type gauge theories
Ali Dehghani, Mohammad Reza Setare, Soodeh Zarepour
We extensively explore three different aspects of Born-Infeld (BI) type nonlinear gauge-invariant modifications of Maxwell's classical electrodynamics (also known as BI-type…
Constraining the generalized uncertainty principle with neutron interferometry
Fabiano Feleppa, Hooman Moradpour, Christian Corda +1
The non-zero minimal length arises in various theories of gravity, leading to the so-called generalized uncertainty principle (GUP). In this short paper we analyze the GUP effects…
Holographic Heat Engines Coupled with Logarithmic Gauge Theory
Soodeh Zarepour
In this paper we study a new class of holographic heat engines via charged AdS black hole solutions of Einstein gravity coupled with logarithmic nonlinear gauge theory. So,…
Hubble tension bounds the GUP and EUP parameters
S. Aghababaei, H. Moradpour, Elias C. Vagenas
In recent years the discrepancy in the value of the Hubble parameter has been growing. Recently, there are works supporting the proposal that the uncertainty principles can solve t…
Non-minimal coupling inspires the Dirac cosmological model
Hooman Moradpour, Hamid Shabani, Amir Hadi Ziaie +1
In the framework of the generalized Rastall theory (GRT), we study the ability of a non-minimal coupling between geometry and matter fields in order to provide a setting which allo…
