Cosmological dynamics of mimetic gravity
Jibitesh Dutta,Jibitesh Dutta,Wompherdeiki Khyllep,Wompherdeiki Khyllep,Emmanuel N. Saridakis,Emmanuel N. Saridakis,Emmanuel N. Saridakis,Nicola Tamanini,Sunny Vagnozzi,Sunny Vagnozzi +9 more
TL;DR: In this article, a detailed investigation of the dynamical behavior of mimetic gravity with a general potential for the mimetic scalar field is presented, which can successfully describe the thermal history of the universe, namely the successive sequence of radiation, matter, and dark energy eras.
Journal ArticleDOI
Cosmological solutions and growth index of matter perturbations in f ( Q ) gravity
Wompherdeiki Khyllep,Wompherdeiki Khyllep,Andronikos Paliathanasis,Andronikos Paliathanasis,Jibitesh Dutta,Jibitesh Dutta +5 more
TL;DR: In this article, the authors considered the power-law form of the cosmological model and analyzed its behavior at both the background and perturbation level, finding that the effective evolution of the model is the same as that of the CDM model for any value of n −1.

Journal ArticleDOI
Scalar-Fluid interacting dark energy: cosmological dynamics beyond the exponential potential
TL;DR: In this paper, the authors extend the dynamical systems analysis of Scalar-Fluid interacting dark energy models performed in C. G. Boehmer et al. by considering scalar field potentials beyond the exponential type.
Journal ArticleDOI
Cosmological dynamics of scalar fields with kinetic corrections: Beyond the exponential potential
TL;DR: Tamanini et al. as mentioned in this paper extended the dynamical systems investigation of cosmological scalar fields characterized by kinetic corrections to arbitrary scalar field potentials and derived general results regarding the corresponding cosmology dynamics.
