Scattering of kinks in Frankensteinian potentials: Kinks as bubbles of exotic mass and phase transitions in oscillon production
Lukáš Rafaj, OndÅej Nicolas KarpÃÅ¡ek, Filip Blaschke
We present a dynamical picture of kink-anti-kink scattering in a pair of special, Frankensteinian potentials made of piece-wise quadratic and linear pieces. Specifically, we focus…
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…
Scattering of kinks in coreless potentials
OndÅej Nicolas KarpÃÅ¡ek, Lukáš Rafaj, Filip Blaschke
We explore the relevance of the central hill for a symmetric double-well potential and its impact on the scattering of kinks in a scalar field theory in (1+1)-dimensions. This regi…
