The cosmological model in gravity with Scalar Field conformity
J. K. Singh, Akanksha Singh, Shaily +1
The homogeneous and isotropic cosmological model in generalized theories associated with scalar field is discussed, which is motivated by the theory of grav…
A constrained cosmological model in gravity
J. K. Singh, Shaily, Ratbay Myrzakulov +1
In this article, we study the expanding nature of universe in the contest of gravity theory, here represents the Ricci scalar and is the matter Lagrangian…
The constrained cosmological model in Lyra geometry
J. K. Singh, Shaily, Shri Ram +2
In this article, we study a flat homogeneous FLRW model in Lyra geometry which is described by a time-dependent displacement vector. We consider an appropriate parametrization of t…
Dynamical analysis of a hyperbolic solution in Scale-covariant theory
Shaily, J. K. Singh, Joao R. L. Santos +1
We study an isotropic flat FLRW-model in Scale-covariant theory of gravity \cite{Canuto:1977zz} which is explained in terms of ordinary and covariant differentiation…
Bouncing cosmology in modified gravity with higher-order curvature terms
J. K. Singh, Harshna Balhara, Kazuharu Bamba +1
A bouncing scenario of a flat homogeneous and isotropic universe is explored by using the reconstruction technique for the power-law parametrization of the Hubble parameter in a mo…
Curvature dominance DE-model in -gravity
G. K. Goswami, Rita Rani, Harshna Balhara +1
We have probed a cosmological model in -gravity, which is a cubic equation in scalar curvature . The terms arise due to nonlinear function are treated as energy due…
Thermodynamic stability and P-V criticality of nonsingular-AdS black holes endowed with clouds of strings
Ashima Sood, Arun Kumar, J. K. Singh +1
We investigate the extended phase space thermodynamics of nonsingular-AdS black holes minimally coupled to clouds of strings in which we consider the cosmological constant () as…
Dynamics of a parametrized dark energy model in gravity
J. K. Singh, Akanksha Singh, G. K. Goswami +1
We investigate a flat FLRW-model in -gravity, which includes the quadratic variation in scalar curvature and the linear term of the trace of the stress-energy tensor $T…
Bouncing universe in Gauss-Bonnet gravity
J. K. Singh, Shaily, Kazuharu Bamba
In this paper, a bouncing cosmological scenario is studied in the background of a flat FLRW model with a specific parametrized hyperbolic form of scale factor in terms of $ t…
