Cosmological dynamics of mimetic gravity
Jibitesh Dutta, Wompherdeiki Khyllep, Emmanuel N. Saridakis +2
We present a detailed investigation of the dynamical behavior of mimetic gravity with a general potential for the mimetic scalar field. Performing a phase-space and stability analy…
Extended Phase Space Analysis of Interacting Dark Energy Models in Loop Quantum Cosmology
Hmar Zonunmawia, Wompherdeiki Khyllep, Nandan Roy +2
The present work deals with the dynamical system investigation of interacting dark energy models (quintessence and phantom) in the framework of Loop Quantum Cosmology by taking int…
Dark energy with a gradient coupling to the dark matter fluid: cosmological dynamics and structure formation
Jibitesh Dutta, Wompherdeiki Khyllep, Nicola Tamanini
We consider scalar field models of dark energy interacting with dark matter through a coupling proportional to the contraction of the four-derivative of the scalar field with the f…
Scalar-Fluid interacting dark energy: cosmological dynamics beyond the exponential potential
Jibitesh Dutta, Wompherdeiki Khyllep, Nicola Tamanini
We extend the dynamical systems analysis of Scalar-Fluid interacting dark energy models performed in C. G. Boehmer et al, Phys. Rev. D 91, 123002 (2015), by considering scalar fiel…
