Cosmology from an exponential dependence on the trace of the energy-momentum tensor -- Numerical approach and cosmological tests
G. Ribeiro, R. Sfair, P. H. R. S. Moraes +2
In this paper, we present the cosmological scenario obtained from gravity by using an exponential dependence on the trace of the energy-momentum tensor. With a numerical a…
Wormholes in Randall-Sundrum braneworld
Ayan Banerjee, P. H. R. S. Moraes, R. A. C. Correa +1
Braneworld models were firstly proposed as a great alternative for the hierarcy problem of particle physics, by allowing gravitons, differently from the other interacting bosons, t…
Phantom fluid supporting traversable wormholes in alternative gravity with extra material terms
P. K. Sahoo, P. H. R. S. Moraes, Parbati Sahoo +1
Wormholes are tunnels connecting different regions in space-time. They were obtained originally as a solution for Einstein's General Relativity theory and according to this theory…
A cosmological scenario from the Starobinsky model within the formalism
P. H. R. S. Moraes, P. K. Sahoo, G. Ribeiro +1
In this paper we derive a novel cosmological model from the theory of gravitation, for which is the Ricci scalar and is the trace of the energy-momentum tensor. We…
Comment on "Cosmological inviability of gravity"
P. H. R. S. Moraes, R. A. C. Correa, G. Ribeiro
The recent article entitled "Cosmological inviability of gravity" [Phys. Rev. D 95 (2017) 123536], by H. Velten and T.R.P. Caramês, claims that the reference "A transition…
The Starobinsky model within the formalism as a cosmological model
P. H. R. S. Moraes, R. A. C. Correa, G. Ribeiro
In this paper we derive a cosmological model from the theory of gravity, for which is the Ricci scalar and is the trace of the energy-momentum tensor. We consider…
