Radial kinks in a Schwarzschild-like geometry
Jean-Guy Caputo, Tomasz Dobrowolski, Jacek Gatlik +1
We study the propagation of a domain wall (kink) of the model in a radially symmetric environment defined by a gravity source. This source deforms the standard Euclidian metr…

Kink movement on a periodic background
Tomasz Dobrowolski, Jacek Gatlik, Panayotis G. Kevrekidis
The behavior of the kink in the sine-Gordon (sG) model in the presence of periodic inhomogeneity is studied. An ansatz is proposed that allows for the construction of a reliable ef…
