Phase transitions in the logarithmic Maxwell O(3)-sigma model
F. C. E. Lima, C. A. S. Almeida
We investigate the presence of topological structures and multiple phase transitions in the O(3)-sigma model with the gauge field governed by Maxwell's term and subject to a so-cal…
Compact-like vortices in isotropic curved spacetime
F. C. E. Lima, C. A. S. Almeida
We introduced a generalized Maxwell-Higgs model in a isotropic spacetime, and we found their stationary solutions using the BPS approach in curved spacetime. In order to in…
Quantum information entropies for a soliton at hyperbolic well
F. C. E. Lima
In this work, the probability uncertainties related to a stationary quantum system with solitonic mass distribution when subjected to deformable hyperbolic potentials are studied.…
Configurational Entropy and braneworlds in f(T,B) gravity
A. R. P. Moreira, F. C. E. Lima, C. A. S. Almeida
The thick brane scenario built on the f(T,B) teleparallel gravity theory was considered for the study of phase transitions, internal structures, and new classes of solutions in a m…
Topological structures in a non-canonical perturbative dynamics of a cuscuton-like model
F. C. E. Lima, A. Yu. Petrov, C. A. S. Almeida
In this work, a possible description for quantum dynamics of the cuscuton within the sigma-model approach is presented. Lower order perturbative corrections and the structure of di…
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…
