Dynamics of viable dark energy models in the presence of Curvature-Matter interactions
Anirban Chatterjee, Rahul Roy, Sayantan Dey +1
In this study, we analyze the dynamics of the interaction between dark matter and curvature-driven dark energy in viable gravity models using the framework of dynamical syst…
Dynamical Stability in presence of non-minimal derivative dependent coupling of -essence field with a relativistic fluid
Kaushik Bhattacharya, Anirban Chatterjee, Saddam Hussain
In this paper we investigate a non-minimal, space-time derivative dependent, coupling between the -essence field and a relativistic fluid using a variational approach. The deriv…
Dynamical analysis of -essence cosmology in the light of Supernova Ia observations
Anirban Chatterjee, Abhijit Bandyopadhyay, Biswajit Jana
In this paper, we analyse the JLA data on Supernova observations in the context of essence dark energy model with Lagrangian , with a constant potential and the dy…
Dynamical stability of K-essence field interacting non-minimally with a perfect fluid
Anirban Chatterjee, Saddam Hussain, Kaushik Bhattacharya
We study models of non-minimally coupled relativistic fluid and -essence scalar field in the background of a flat Friedmann-Lemaitre-Robertson-Walker universe. The non-minimal c…
Time-dependent diffusive interactions between dark matter and dark energy in the context of essence cosmology
Abhijit Bandyopadhyay, Anirban Chatterjee
We investigated the scenario of time-dependent diffusive interaction between dark matter and dark energy and showed that such a model can be accommodated within the observations of…
Implications of JLA data for essence model of dark energy with given equation of state
Abhijit Bandyopadhyay, Anirban Chatterjee
We investigated implications of recently released `Joint Light-curve Analysis' (JLA) supernova Ia (SNe Ia) data for dark energy models with time varying equation of state of dark e…
Diffusive dark matter and dark energy scenario and essence in the context of Supernova Ia observations
Abhijit Bandyopadhyay, Anirban Chatterjee
We consider a unified model of interacting dark matter and dark energy to account for coincidence of present day dark energy and dark matter densities. We assume dark energy to be…
Realising Interactions Between Dark Matter and Dark Energy Using -essence Cosmology
Abhijit Bandyopadhyay, Anirban Chatterjee
In this paper we exploit dynamics of a essence scalar field to realise interactions between dark components of universe resulting in a evolution consistent with observed featur…
