Analytical general solutions for static wormholes in gravity
P. H. R. S. Moraes, R. A. C. Correa, R. V. Lobato
Originally proposed as a tool for teaching the general theory of relativity, wormholes are today approached in many different ways and are seeing as an efficient alternative for in…
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…
Cosmological scenarios from multiquintessence
R. A. C. Correa, P. H. R. S. Moraes, A. de Souza Dutra +2
In this work we derive and analyse cosmological scenarios coming from multi-component scalar field models. We consider a direct sum of a sine-Gordon with a Z2 model, and also a com…
Refinements of the Weyl pure geometrical thick branes from information-entropic measure
R. A. C. Correa, D. M. Dantas, P. H. R. S. Moraes +2
This letter aims to analyse the so-called configurational entropy in the Weyl pure geometrical thick brane model. The Weyl structure plays a prominent role in the thickness of this…
Evading the non-continuity equation in the f(R, T) formalism
P. H. R. S. Moraes, R. A. C. Correa
We present a new approach for the formalism, by exploring the extra terms of its effective energy-momentum tensor , namely . Those arise from…
Configurational entropy as a bounding of Gauss-Bonnet braneworld models
R. A. C. Correa, P. H. R. S. Moraes, A. de Souza Dutra +2
Configurational entropy has been revealed as a reliable method for constraining some parameters of a given model [Phys. Rev. D \textbf{92} (2015) 126005, Eur. Phys. J. C \textbf{76…
