Kink-antikink collisions in hyper-massive models
F. M. Hahne, P. Klimas
We study topological kinks and their interactions in a family of scalar field models with a double well potential parametrized by the mass of small perturbations around the vacua,…
Scattering of compact kinks
F. M. Hahne, P. Klimas
We study the scattering processes of kink-antikink and kink-kink pairs in a field theory model with non-differentiable potential at its minima. The kink-antikink scattering include…
Signum-Gordon shock waves in (2+1) and (3+1) dimensions
Pawel Klimas, João Saldanha Streibel
This study introduces novel, exact solutions to the scalar field Signum-Gordon equation that feature a discontinuity near the light cone. These solutions, applicable in higher spat…
Compact kink and its interaction with compact oscillons
F. M. Hahne, P. Klimas
We study compact kinks and its interaction with compact oscillons in models with non-analytic potentials. Oscillon-like excitations are the main ingredients of the radiation field.…
Nodal compact -ball/-shell in the nonlinear sigma model
P. Klimas, N. Sawado, S. Yanai
Nodal, excited compactons in the models with V-shaped potentials are analyzed. It is shown that the solutions exist as compact -balls and -shells. The solutio…
Compact Q-balls and Q-shells in a multi-component model
P. Klimas, L. C. Kubaski, N. Sawado +1
Coupled multi-component models with V-shaped potentials are analyzed. It is shown that the model has solutions being combinations of compact Q-balls and Q-shells. T…
