Thawing in a coupled quintessence model
M. Honardoost, H. Mohseni Sadjadi, H. R. Sepangi
We consider the thawing model in the framework of coupled quintessence model. The effective potential has symmetry which is broken spontaneously when the dark matter density…
Symmetry breaking and the onset of cosmic acceleration in scalar field models
H. Mohseni Sadjadi, M. Honardoost, H. R. Sepangi
We propose a new scenario for the onset of positive acceleration of our Universe based on symmetry breaking in coupled dark energy scalar field model. In a symmetry breaking proces…
Cosmology of a Lorentz violating Galileon theory
Zahra Haghani, Tiberiu Harko, Hamid Reza Sepangi +1
We modify the scalar Einstein-aether theory by breaking the Lorentz invariance of a gravitational theory coupled to a Galileon type scalar field. This is done by introducing a Lagr…
