Deformation of sine-Gordon two-soliton solutions in kink-antikink configurations
Aliakbar Moradi Marjaneh, Danial Saadatmand, Fabiano C. Simas +2
In this work, we construct analytical kink-antikink configurations in the non-integrable model by mapping exact solutions of the integrable sine-Gordon system vi…
Kinks in generalized scalar field models and their scattering properties
D. Bazeia, A. S. Lobão, Fabiano C. Simas
This work investigates kink solutions in one-dimensional scalar field theories. We begin with a review of the formalism used to obtain these solutions, presenting the BPS formalism…
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…
