Kink Dynamics in a Parametric ${\varphi }^6$ System: A Model With Controllably Many Internal Modes

A. Demirkaya, R. Decker, P. G. Kevrekidis +2

We explore a variant of the ${\varphi }^6$ model originally proposed in Phys.\ Rev.\ D {\bf 12}, 1606 (1975) as a prototypical, so-called, "bag" model in which domain walls play the role of…
