Inflation with a quartic potential in the framework of Einstein-Gauss-Bonnet gravity

Ekaterina O. Pozdeeva, Mayukh Raj Gangopadhyay, Mohammad Sami +2

We investigate inflationary dynamics in the framework of the Einstein-Gauss-Bonnet gravity. In the model under consideration, the inflaton field is non-minimally coupled to the Gau…

Modified Theory of Gravity and Clustering of Multi-Component System of Galaxies

Mir Hameeda, Behnam Pourhassan, Mir Faizal +3

In this paper, we analyze the clustering of galaxies using a modified theory of gravity, in which the field content of general relativity has been be increased. This increasing in…

Baryogenesis in the paradigm of quintessential inflation

Safia Ahmad, Antonio De Felice, Nur Jaman +2

We explore the possibility of baryogenesis in the framework of quintessential inflation. We focus on the model independent features of the underlying paradigm and demonstrate that…

Stability analysis of de Sitter solutions in models with the Gauss-Bonnet term

Ekaterina O. Pozdeeva, Mohammad Sami, Alexey V. Toporensky +1

We investigate the scalar field dynamics of models with nonminimally coupled scalar fields in the presence of the Gauss-Bonnet term and derive the structure of the effective potent…

Superpotential method for chiral cosmological models connected with modified gravity

S. V. Chervon, I. V. Fomin, E. O. Pozdeeva +2

We consider the Chiral Cosmological Models (CCMs) and modified gravity theories associated with them. Generalization of the superpotential method for a general CCM with several sca…

Semiconformal symmetry- A new symmetry of the spacetime manifold of the general relativity

Musavvir Ali, Naeem Ahmad Pundeer, Zafar Ahsan

In this paper we have introduced a new symmetry property of spacetime which is named as semiconformal curvature collineation, and its relationship with other known symmetry propert…

Emergence of cosmological scaling behavior in asymptotic regime

M. A. Skugoreva, M. Sami, N. Jaman

In this paper we consider a scalar field system with a class of potentials given by the expression, ; for which $…

Bigravity and Horndeski gravity connected by a disformal coupling

Radouane Gannouji, Md. Wali Hossain, Nur Jaman +1

In this paper, we have studied bi-gravity theory in a very specific limit where we focused only on one degree of freedom generated by the massive graviton. We have analyzed the mod…

Cosmic acceleration sourced by modification of gravity without extra degrees of freedom

Abhineet Agarwal, R. Myrzakulov, S. K. J. Pacif +2

In this paper, we investigate a scenario in which late time cosmic acceleration might arise due to coupling between dark matter and baryonic matter without resorting to dark energy…

Relic gravitational waves from Quintessential Inflation

Safia Ahmad, R. Myrzakulov, M. Sami

We study relic gravitational waves in the paradigm of quintessential inflation. In this framework, irrespective of the underlying model, inflation is followed by the kinetic regime…
