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…
Quasi Q-Balls in massless scalar fields
Tomasz Romanczukiewicz, Yakov Shnir
We study long-term evolution of radiating quasi-Q-balls in 1+1 dimensional models without mass threshold. Two different models are considered, the model with a rational modificatio…
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…
Resonance structures in kink-antikink collisions in a deformed sine-Gordon model
Patrick Dorey, Anastasia Gorina, Ilya Perapechka +2
We study kink-antikink collisions in a model which interpolates smoothly between the completely integrable sine-Gordon theory, the model, and a -like model with three de…
Some Recent Developments on Kink Collisions and Related Topics
Tomasz Romanczukiewicz, Yakov Shnir
We review recent works on modeling of dynamics of kinks in 1+1 dimensional theory and other related models, like sine-Gordon model or theory. We discuss how the spectra…
Oscillons in the presence of external potential
Tomasz Romańczukiewicz, Yakov Shnir
We discuss similarity between oscillons and oscillational mode in perturbed . For small depths of the perturbing potential it is difficult to distinguish between oscillons and…
