Resonance with quasinormal modes in long-range kinks' collisions
J. G. F. Campos, Azadeh Mohammadi, T. Romanczukiewicz
We consider a rational scalar field model in (1+1)-dimensions where the long-range character of the kinks is controllable. We show via numerical simulations that kinks with long-ra…

On the localized and delocalized modes in kink-antikink interactions: a toy model
Carlos E. S. Santos, João G. F. Campos, Azadeh Mohammadi
This study deals with a piecewise scalar field theory in dimensions. The scalar field potential is designed with a triple-well shape, engendering kink solutions with…

Collective coordinates method for long-range kink collisions
J. G. F. Campos, A. Mohammadi, T. Romanczukiewicz
In this paper, we explored a class of potentials with three minima that support kink solutions exhibiting one long-range tail. We analyzed antikink-kink interactions using an effec…
