DBI inflation with a non-minimally coupled Gauss-Bonnet term
Kourosh Nozari, Narges Rashidi
We study the inflation in a model with a Gauss-Bonnet term which is non-minimally coupled to a DBI field. We study the spectrum of the primordial perturbations in detail. The non-G…
Non-Minimal Braneworld Inflation after the Planck
Kourosh Nozari, Narges Rashidi
The recently released Planck data have constrained 4-dimensional inflationary parameters even more accurately than ever. We consider an extension of the braneworld model with induc…
Cosmological dynamics of a non-minimally coupled bulk scalar field in DGP setup
Kourosh Nozari, Narges Rashidi
We consider cosmological dynamics of a canonical bulk scalar field, which is coupled non-minimally to 5-dimensional Ricci scalar in a DGP setup. We show that presence of this non-m…
Gauss-Bonnet Braneworld Cosmology with Modified Induced Gravity on the Brane
Kourosh Nozari, Faeze Kiani, Narges Rashidi
We analyze the background cosmology for an extension of the DGP gravity with Gauss-Bonnet term in the bulk and gravity on the brane. We investigate implications of this setu…
Some Aspects of Tachyon Field Cosmology
Kourosh Nozari, Narges Rshidi
We study inflation, perturbations, non-gaussinity and late-time cosmological dynamics of a tachyon field both minimally and non-minimally coupled to gravity. By analyzing the param…
Cosmological dynamics of a hybrid chameleon scenario
Kourosh Nozari, N. Rashidi
We consider a hybrid scalar field which is non-minimally coupled to the matter and models a chameleon cosmology. By introducing an effective potential, we study the dependence of t…
