Emergent cosmos in Einstein–Cartan theory
/ Hadi, H. ; Heydarzade, Y. ; Hashemi, M. ; Darabi, F.
Based on Padmanabhan’s proposal, the accelerated expansion of the universe can be driven by the difference between the surface and bulk degrees of freedom in a region of space, described by the relation dV/dt=NsurNbulk where Nsur and Nbulk=Nem+Nde are the degrees of freedom assigned to the surface area and the matter–energy content inside the bulk such that the indices “em” and “de” represent energymomentum and dark energy, respectively.

Einstein and Rastall theories of gravitation in comparison
/ Darabi, F. ; Moradpour, H. ; Licata, I. ; Heydarzade, Y. ; et al
We profit by a recent paper of Visser claiming that Rastall gravity is equivalent to Einstein gravity to compare the two gravitational theories in a general way. [...]

Inflation via logarithmic entropycorrected holographic dark energy model
/ Darabi, F. ; Felegary, F. ; Setare, M. R.
We study the inflation in terms of the logarithmic entropycorrected holographic dark energy (LECHDE) model with future event horizon, particle horizon, and Hubble horizon cutoffs, and we compare the results with those obtained in the study of inflation by the holographic dark energy HDE model.
