1. 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 so-called BPS method in order to obtain topological defects for a complex scalar field Lagrangian introduced by Trullinger and Subbaswamy. [...]

3. Evading the non-continuity equation in the f ( R ,  T ) cosmology / Moraes, P. H. R. S. ; Correa, R. A. C. ; Ribeiro, G.
We present a new approach for the f ( R ,  T ) gravity formalism, by thoroughly exploring the extra terms of its effective energy-momentum tensor Tμνeff , which we name T~μν , so that Tμνeff=Tμν+T~μν , with Tμν being the usual energy-momentum tensor of matter. [...]

4. Supersymmetry and fermionic modes in an oscillon background / Correa, R.A.C. ; Ospedal, L.P.R. ; de Paula, W. ; Helayël-Neto, J.A.
The excitations referred to as oscillons are long-lived time-dependent field configurations which emerge dynamically from non-linear field theories. [...]
