Exact BPS double-kinks in generalized $I ¨ ^{4}$ , $I ¨ ^{6}$ 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 $I ¨ $ whose kinematics is modified by a generalizing function $f (I ¨ )$ . After briefly reviewing its Bogomol'n…

Sine-Gordon kink lattice

E. da Hora, C. dos Santos, Fabiano C. Simas

We consider an extended model with two real scalar fields, $I ¨ (x, t)$ and $I ¨ (x, t)$ . The first sector is controlled by the sine-Gordon superpotential, while the second field is subm…

Vacuum state perturbed by an oscillon: composite configurations in $I ¨ ^{4}$ model

Fabiano C. Simas, E. da Hora

We examine the evolution of a vacuum configuration when perturbed by an oscillon. We consider the $I ¨ ^{4}$ scenario with a single scalar field only. For highly excited oscillons, we…
