A General Method for Transforming Nonphysical Configurations in BPS States
/ Correa, R. A. C. ; Santos, J. R. L. ; Dutra, A. de Souza ; Winter, O. C.
In this work, we apply the socalled BPS method in order to obtain topological defects for a complex scalar field Lagrangian introduced by Trullinger and Subbaswamy. [...]

Building analytical threefield cosmological models
/ Santos, J. R. L. ; Moraes, P. H. R. S. ; Ferreira, D. A. ; Neta, D. C. Vilar
A difficult task to deal with is the analytical treatment of models composed of three real scalar fields, as their equations of motion are in general coupled and hard to integrate. [...]

Cosmology in the Universe with Distance Dependent LorentzViolating Background
/ Brito, F. A. ; Almeida, C. A. G. ; Anacleto, M. A. ; Passos, E. ; et al
We consider a cosmological setup with inflaton in the presence of a redshift dependent Lorentzviolating timelike background to address the inflationary regime and other phases of the Universe. [...]

A complete cosmological scenario from f(R,Tϕ) gravity theory
/ Moraes, P. H. R. S. ; Santos, J. R. L.
Recent elaborated by Harko et al., the f ( R , T ) theories of gravity allow one to contemplate an optimistic alternative to dark energy, for which R and T stand for the Ricci scalar and the trace of the energymomentum tensor, respectively. [...]
