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…

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 …
