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…
Ward identity preserving approach for investigation of phonon spectrum with self-energy and vertex corrections
Sudhakar Pandey
We propose an approach for investigating the many body effects on phonon spectrum in an electron-phonon coupled system by taking into account the electron self-energy and vertex co…
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…
