Half-line kink scattering in the $ϕ^{4}$ 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 $ϕ^{4}$ model, restricted to the half-line. Here we consider singular solutions that…

Scattering of sine-Gordon kinks with internal structure in an extended nonlinear $O (3)$ sigma model

Adalto R. Gomes, Fabiano C. Simas

In this paper, we present topological defects in $(1, 1)$ dimensions, described by an extended nonlinear $O (3)$ sigma model. We consider spherical coordinates $(ϕ, χ)$ in the $S^{2}$ i…
