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…
Accelerated cosmos in a non-extensive setup
H. Moradpour, Alexander Bonilla, Everton M. C. Abreu +1
Here, we consider a flat FRW universe whose its horizon entropy meets the Rényi entropy of non-extensive systems. In our model, the ordinary energy-momentum conservation law is not…
Third gravitational wave polarization mode in Rastall theory and analogy with f(R) theories
H. Moradpour, C. Corda, I. Licata
The recent starting of the gravitational wave (GW) astronomy with the events GW150914, GW151226, GW170104, and the very recent GW170814 and GW170817 seems to be fundamental not onl…
Relativistic Bose--Einstein condensates thin-shell wormholes
M. G. Richarte, I. G. Salako, J. P. Morais Graça +2
We construct traversable thin-shell wormholes which are asymptotically Ads/dS applying the cut and paste procedure for the case of an acoustic metric created by a relativistic Bose…
The commutator algebra of covariant derivative as general framework for extended gravity. The Rastall theory case and the role of the torsion
I. Licata, H. Moradpour, C. Corda
In this short review, we discuss the approach of the commutator algebra of covariant derivative to analyse the gravitational theories, starting from the standard Einstein's general…
Spherically symmetric solutions in a FRW background
H. Moradpour, N. Riazi
We impose perfect fluid concept along with slow expansion approximation to derive new solutions which, considering non-static spherically symmetric metrics, can be treated as Black…
