Oscillons from -balls
F. Blaschke, T. RomaÅczukiewicz, K. SÅawiÅska +1
Using Renormalization Group Theory we show that oscillons in (1+1)-dimensions can be obtained, at the leading nonlinear order, from -balls of universal complex field theories. F…

Oscillons from -balls through renormalization
F. Blaschke, T. RomaÅczukiewicz, K. SÅawiÅska +1
Using a renormalization-inspired perturbation expansion we show that oscillons in a generic field theory in (1+1) dimensions arise as dressed -balls of a universal (up to the le…

Kink-kink solutions in BPS impurity models
Katarzyna SÅawiÅska
We show that BPS-impurity theories may support BPS kink-kink solutions i.e., an energetically degenerated family of solutions describing two kinks at any mutual distance. This requ…
