Kinks and double-kinks in generalized $ϕ^{4}$ -and $ϕ^{8}$ -models

F. C. E. Lima, R. Casana, C. A. S. Almeida

Examining the $ϕ^{4}$ and $ϕ^{8}$ models within a two-dimensional framework in the flat spacetime and embracing a theory with unconventional kinetic terms, one investigates the eme…

On the asymmetric non-canonical braneworld in five dimensions

F. C. E. Lima, F. M. Belchior, C. A. S. Almeida +1

Revisiting Einstein's gravitational theory, we build a five-dimensional braneworld. Within this framework, one announces the appearance of symmetric and asymmetric domain walls. Fu…

Physical aspects of the deformation of $Z_{2}$ kinks in a generalized $ϕ^{4}$ model

F. C. E. Lima, C. A. S. Almeida, Rodolfo Casana

We study a generalized $ϕ^{4}$ model that gives rise to BPS kink/antikink configurations with compacton-like profiles. One observes that the positive parameter controlling the genera…
