Half-line kink scattering in the model with Dirichlet boundary conditions
Jairo S. Santos, Fabiano C. Simas, Adalto R. Gomes
In this work, we investigate the dynamics of a scalar field in the nonintegrable model, restricted to the half-line. Here we consider singular solutions that…
Sine-Gordon kink lattice
E. da Hora, C. dos Santos, Fabiano C. Simas
We consider an extended model with two real scalar fields, and . The first sector is controlled by the sine-Gordon superpotential, while the second field is submit…
Scattering of sine-Gordon kinks with internal structure in an extended nonlinear sigma model
Adalto R. Gomes, Fabiano C. Simas
In this paper, we present topological defects in dimensions, described by an extended nonlinear sigma model. We consider spherical coordinates in the i…
Fermion bound states from Yukawa coupling with periodic bosonic background
Dionisio Bazeia, Fabiano C. Simas
The Yukawa coupling of fermions with a periodic bosonic background is shown to give rise to several bound states to the fermionic spectrum, with some bound states gluing together a…
Vacuum state perturbed by an oscillon: composite configurations in model
Fabiano C. Simas, E. da Hora
We examine the evolution of a vacuum configuration when perturbed by an oscillon. We consider the scenario with a single scalar field only. For highly excited oscillons, we f…
Scattering of kinks in scalar-field models with higher-order self-interactions
Aliakbar Moradi Marjaneh, Fabiano C. Simas, D. Bazeia
Higher-order scalar field models in two dimensions, including the model, have been researched. It has been shown that for some special cases of the minima positions of the po…
