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…
Cosmological solutions and growth index of matter perturbations in gravity
Wompherdeiki Khyllep, Andronikos Paliathanasis, Jibitesh Dutta
The present work studies one of Einstein's alternative formulations based on the non-metricity scalar generalized as theory. More specifically, we consider the power-law…
Cosmological dynamics and bifurcation analysis of the general non-minimally coupled scalar field models
Wompherdeiki Khyllep, Jibitesh Dutta
Non-minimally coupled scalar field models are well-known for providing interesting cosmological features. These include a late time dark energy behavior, a phantom dark energy evol…
