D-bound and Bekenstein bound for McVittie solution surrounded by dark energy cosmological fields
H. Hadi, Y. Heydarzade, F. Darabi +1
The cosmological candidate fields for dark energy as quintessence, phantom and cosmological constant, are studied in terms of an entropic hypothesis imposed on the McVittie solutio…
Bounding f(R,T) gravity by particle creation
K. Asadiyan, F. Darabi, P. Pedram +1
We consider the possibility of the quantum vacuum states in f(R,T) gravity. Particularly, we study the Bogoliubov transformations associated to different vacuum states for some f(R…
Einstein and Rastall Theories of Gravitation in Comparison
F. Darabi, H. Moradpour, I. Licata +2
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. Our conclusions ar…
Braneworld Black Holes and Entropy Bounds
Y. Heydarzade, H. Hadi, C. Corda +1
The Bousso's D-bound entropy for the various possible black hole solutions on a 4-dimensional brane is checked. It is found that the D-bound entropy here is apparently different fr…
Signature Change by GUP
T. Ghaneh, F. Darabi, H. Motavalli
We revisit the issue of continuous signature transition from Euclidean to Lorentzian metrics in a cosmological model described by FRW metric minimally coupled with a self interacti…
One-loop quantum cosmological correction to the gravitational constant using the kink solution in de Sitter universe
F. Darabi, S. Jalalzadeh
In this paper, we show the equivalence between a classical static scalar field theory and the (closed) de Sitter cosmological model whose potential represents shape invariance prop…
