Realizing late-time cosmology in the context of Dynamical Stability Approach
Anirban Chatterjee, Saddam Hussain, Kaushik Bhattacharya
We examine the scenario of non-minimally coupled relativistic fluid and -essence scalar field in a flat Friedmann-Lemaitre-Robertson-Walker universe. By adding a non-minimal cou…
Dynamical stability in models where dark matter and dark energy are non-minimally coupled to curvature
Saddam Hussain, Anirban Chatterjee, Kaushik Bhattacharya
This work explores the dynamical stability of cosmological models where dark matter and dark energy can non-minimally couple to spacetime (scalar) curvature. Two different scenario…
Observational constraints on non-minimally coupled curvature-matter models of gravity from the analysis of Pantheon data
Biswajit Jana, Anirban Chatterjee, Kumar Ravi +1
We considered non-minimally coupled curvature-matter models of gravity in a FRW universe filled with perfect fluid and investigated its cosmological implications in the light of Pa…
Modified scaling in -essence model in interacting dark energy - dark matter scenario
Anirban Chatterjee, Biswajit Jana, Abhijit Bandyopadhyay
It has been shown by \textit{Scherrer and Putter et.al} that, when dynamics of dark energy is driven by a homogeneous essence scalar field , with a Lagrangian of the form $L…
Ghost condensates and pure kinetic -essence condensates in presence of field-fluid non-minimal coupling in the dark sector
Saddam Hussain, Anirban Chatterjee, Kaushik Bhattacharya
In this article we try to find out the conditions when a ghost field in conjunction with a barotropic fluid produces a stable accelerating expansion phase of the universe. It is se…
The nature of cosmological metric perturbations in presence of gravitational particle production
Kaushik Bhattacharya, Anirban Chatterjee, Saddam Hussain
The present paper tries to answer the question: Can a de Sitter phase in presence of radiation be a competitor of the standard inflationary paradigm for the early universe? This ki…
