Ghost Dark Energy in Tsallis and Barrow Cosmology
Esmaeil Ebrahimi, Ahmad Sheykhi
According to the thermodynamics-gravity conjecture, any modification to the entropy expression leads to the modified cosmological field equations. Based on this, we investigate the…
Non-Linearly Interacting Ghost Dark Energy in Brans-Dicke Cosmology
E. Ebrahimi, H. Golchin
In this paper we extend the form of interaction term into the non-linear regime in the ghost dark energy model. A general form of non-linear interaction term is presented and cosmi…
Interacting Dark Energy: Dynamical System Analysis
Hanif Golchin, Sara Jamali, Esmaeil Ebrahimi
We investigate the impacts of interaction between dark matter and dark energy in the context of two dark energy models, holographic and ghost dark energy. In fact, using the dynami…
Generalized ghost dark energy in Brans-Dicke theory
A. Sheykhi, E. Ebrahimi, Y. Yosefi
It was argued that the vacuum energy of the Veneziano ghost field of QCD, in a time-dependent background, can be written in the general form, , where is the Hubble…
Interacting generalized ghost dark energy in non-flat universe
Esmaeil Ebrahimi, Ahmad Sheykhi, Hamzeh Alavirad
We investigate the generalized Quantum Chromodynamics (QCD) ghost model of dark energy in the framework of Einstein gravity. First, we study the non-interacting generalized ghost d…
