Scattering of kinks in Frankensteinian potentials: Kinks as bubbles of exotic mass and phase transitions in oscillon production
Lukáš Rafaj, Ondřej Nicolas Karpíšek, 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…

Scattering of kinks in coreless potentials
Ondřej Nicolas Karpíšek, 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…

Mechanization of scalar field theory in (1+1)-dimensions: BPS mech-kinks and their scattering
Filip Blaschke, Ondřej Nicolas Karpíšek, Lukáš Rafaj
We present an updated version of a general-purpose collective coordinate model that aims to fully map out the dynamics of a single scalar field in (1+1)-dimensions. This is achieve…
