General solution of a cosmological model induced from higher dimensions using a kinematical constraint
Ozgur Akarsu, Tekin Dereli, Nihan Katirci +1
In a recent study Akarsu and Dereli (Gen. Relativ. Gravit. 45:1211, 2013) discussed the dynamical reduction of a higher dimensional cosmological model which is augmented by a kinem…

Accelerated expansion of the Universe a la the Stueckelberg mechanism
Ozgur Akarsu, Metin Arik, Nihan Katirci +1
We investigate a cosmological model in which the Stueckelberg fields are non-minimally coupled to the scalar curvature in a gauge invariant manner. We present not only a solution t…

More on loops in reheating: Non-gaussianities and tensor power spectrum
N. Katirci, A. Kaya, M. Tarman
We consider the single field chaotic m^2ϕ^2 inflationary model with a period of preheating, where the inflaton decays to another scalar field χ in the parametric resonance regime.…
