Observational predictions of inflationary model in spatially covariant gravity with two tensorial degrees of freedom for gravity
Saikat Chakraborty, Khamphee Karwan, Jakkrit Sangtawee
We study the inflationary model constructed from a Spatially Covariant Gravity (SCG). The Lagrangian for the SCG in our consideration is expressed as the polynomial of irreducible…
Dynamical Analysis of the Dirac-Born-Infeld type of Tachyon field minimally coupled with barotropic fluid using EOS parametrization of a field
Saddam Hussain, Saikat Chakraborty, Nandan Roy +1
In this paper, we present a dynamical system analysis of the tachyon dark energy model by parametrization of the equation of state (EoS) of the dark energy. The choice of parametri…
Scalar field evolution at background and perturbation levels for a broad class of potentials
Genly Leon, Saikat Chakraborty, Sayantan Ghosh +3
In this paper, we investigate a non-interacting scalar field cosmology with an arbitrary potential using the -deviser method that relies on the differentiability properties of t…
Global phase space analysis for a class of single scalar field bouncing solutions in general relativity
A. S. Agrawal, Saikat Chakraborty, B. Mishra +2
We carry out a compact phase space analysis of a non-canonical scalar field theory whose Lagrangian is of the form within general relativity. In particular, we focus on…
Dynamical systems analysis of tachyon dark energy model from a new perspective
Saddam Hussain, Saikat Chakraborty, Nandan Roy +1
In this work we present a new scheme to study the tachyon dark energy model using dynamical systems analysis by considering parametrization of the equation of state(EoS) of the dar…
