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…

Amplitude modulations and resonant decay of excited oscillons
F. Blaschke, T. Romańczukiewicz, K. Sławińska +1
We show that the decay of strongly excited oscillons in a single vacuum model reveals a chaotic, fractal-like pattern very much like one found in kink-antikink collision in the $ϕ^…

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…
