Exact BPS double-kinks in generalized $ϕ^{4}$ , $ϕ^{6}$ and sine-Gordon models

R. Casana, E. da Hora, F. C. Simas

We consider a $(1 + 1)$ -dimensional theory with a single real scalar field $ϕ$ whose kinematics is modified by a generalizing function $f (ϕ)$ . After briefly reviewing its Bogomol'nyi…

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…

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…
