A Unified Dynamical Systems Framework for Cosmology in Gravity: Generic Features Beyond the Coincident Gauge
Jibitesh Dutta, Wompherdeiki Khyllep, Saikat Chakraborty +2
We present a unified dynamical systems framework for spatially flat FLRW cosmology in gravity, covering all three connection branches via a single set of Hubble-normalised v…
Modelling the Accelerating Universe with Gravity: Observational Consistency
S. A. Narawade, S. H. Shekh, B. Mishra +2
In this paper, we present a cosmological model within the framework of symmetric teleparallel gravity, focusing on gravity, where represents the non-metricity scalar. Ut…
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…
Cosmology in gravity: A unified dynamical system analysis at background and perturbation levels
Wompherdeiki Khyllep, Jibitesh Dutta, Emmanuel N. Saridakis +1
Motivated by the fact that cosmological models based on gravity are very efficient in fitting observational datasets at both background and perturbation levels, we perform a…
Background evolution and growth of structures in interacting dark energy through dynamical system analysis
Wompherdeiki Khyllep, Jibitesh Dutta, Spyros Basilakos +1
We apply the formalism of dynamical system analysis to investigate the evolution of interacting dark energy scenarios at the background and perturbation levels in a unified way. Si…
Interacting quintessence in light of Generalized Uncertainty Principle: Cosmological perturbations and dynamics
Andronikos Paliathanasis, Genly Leon, Wompherdeiki Khyllep +2
We consider a cosmological scenario endowed with an interaction between the universe's dark components dark matter and dark energy. Specifically, we assume the dark matter comp…
