New class of solutions in the non-minimal O(3)-sigma model
F. C. E. Lima, C. A. S. Almeida
For the study of topological vortices with non-minimal coupling, we built a kind of non-canonical O(3)-sigma model, with a Maxwell term modified by a dielectric function. Through t…
Vortex solutions in nonpolynomial scalar QED
F. C. E. Lima, A. Yu. Petrov, C. A. S. Almeida
In order to investigate possible topological vortex structures in generalized models, we developed a perturbative generation approach for scalar-vector theories. We demonstrate exp…
Thick brane in f(T,B) gravity
A. R. P. Moreira, J. E. G. Silva, F. C. E. Lima +1
In this paper, we explore the five-dimensional f(T,B) teleparallel modified gravity with f_1(T,B)=T+k_1B^{n_1} and f_2(T,B)=B+k_2T^{n_2} in the brane scenario. Asymptotically, the…
Correlations between emission events in Rainbow Gravity
D. A. Gomes, F. C. E. Lima, C. A. S. Almeida
In this work, we study emission correlations in Rainbow Gravity (RG) black holes known to have black hole remnants. Non-thermal corrections are responsible for generating non-zero…
New class of solutions of a generalized -sigma Chern-Simons model
F. C. E. Lima, D. M. Dantas, C. A. S. Almeida
In this work, we investigated the existence of compacton-like configuration in the O(3)-sigma model. We consider a minimally coupled O(3)-sigma model with a gauge field governed by…
Continuously transforming kinks into compactons in the O(3)-sigma model
F. C. E. Lima, D. A. Gomes, C. A. S. Almeida
In this work, we investigate the solutions of vortices in the O(3)-sigma model with the gauge field governed by the Chern-Simons term and subject to a hyperbolic self-dual potentia…
