Quark-hadron phase transition in Brans-Dicke brane gravity
K. Atazadeh, A. M. Ghezelbash, H. R. Sepangi
A standard picture in cosmology has been emerging over the past decade in which a phase transition, associated with chiral symmetry breaking after the electroweak transition, has o…
Energy conditions in f(R) gravity and Brans-Dicke theories
K. Atazadeh, A. Khaleghi, H. R. Sepangi +1
The equivalence between f(R) gravity and scalar-tensor theories is invoked to study the null, strong, weak and dominant energy conditions in Brans-Dicke theory. We consider the val…
Accelerating universe in brane gravity
K. Atazadeh, M. Farhoudi, H. R. Sepangi
We study a 5-dimensional brane gravity within the framework of scalar-tensor type theories. We show that such a model predicts, for a certain choice of …
Curvature corrections in DGP brane cosmology
K. Atazadeh, H. R. Sepangi
We consider a DGP inspired brane scenario where the action on the brane is augmented by a function of the Ricci scalar, . The cosmological implications that such a sce…
Noncommutativity, generalized uncertainty principle and FRW cosmology
A. Bina, K. Atazadeh, S. Jalalzadeh
We consider the effects of noncommutativity and the generalized uncertainty principle on the FRW cosmology with a scalar field. We show that, the cosmological constant problem and…
Modified gravity inspired DGP brane cosmology
K. Atazadeh, H. R. Sepangi
We consider a DGP brane scenario where a scalar field is present on the brane through the introduction of a scalar potential, itself motivated by the notion of modified gravity. Th…
