Bouncing universe with the non-minimally coupled quintom matter on the warped DGP Brane
Kourosh Nozari, M R Setare, Tahereh Azizi +1
We construct a quintom dark energy model with two non-minimally coupled scalar fields, one quintessence and the other phantom field, confined on the warped DGP brane. We study some…
Screening Length of Rotating Heavy Meson from AdS/CFT
J. Sadeghi, S. Heshmatian
In this paper we consider a quark-antiquark () pair which can be interpreted as a meson in =4 SYM thermal plasma. We assume that the string moves at speed…
Reconstructing a String-Inspired Non-minimally Coupled Quintom Model
M R Setare, J Sadeghi, A R Amani
Motivated by the recent work of Zhang and Chen \cite{bin}, we generalize their work to the non-minimally coupled case. We consider a quintom model of dark energy with a single scal…
A Non-minimally Coupled Quintom Dark Energy Model on the Warped DGP Brane
Kourosh Nozari, M. R. Setare, Tahereh Azizi +1
We study dynamics of equation of state parameter for a non-minimally coupled quintom dark energy component on the warped DGP brane. We investigate crossing of the cosmological cons…

A Lorentz Invariance Violating Cosmology on the DGP Brane
Kourosh Nozari, S. Davood Sadatian
We study cosmological implications of a Lorentz invariance violating DGP-inspired braneworld scenario. A minimally coupled scalar field and a single, fixed-norm, Lorentz-violating…
Late-time acceleration and Phantom Divide Line Crossing with Non-minimal Coupling and Lorentz Invariance Violation
Kourosh Nozari, S. Davood Sadatian
We consider two alternative dark energy models: a Lorentz invariance preserving model with a nonminimally coupled scalar field and a Lorentz invariance violating model with a minim…
Gravitational Uncertainty and Black Hole Remnants
Kourosh Nozari, S. Hamid Mehdipour
Possible existence of black holes remnants provides a suitable candidates for dark matter. In this paper we study the possibility of existence for such remnants. We consider quantu…
The solution of tachyon inflation in curved universe
J. Sadeghi, A. R. Amani
In this paper, we have considered the curved universe which is filled by tachyonic field. We have found the exact solutions for the field, pressure, density, and scale factor and s…
Drag Force of Moving Quark at The N=2 Supergravity
J. Sadeghi, B. Pourhassan
In this paper we consider a moving quark in the thermal plasma at the N=2 Supergravity theory. By using the AdS/CFT correspondence we obtain energy loss of the quark. Then we consi…
