Orbit based procedure for doublets of scalar fields and the emergence of triple kinks and other defects

Abstract

In this work we offer an approach to enlarge the number of exactly solvable models with two real scalar fields in (1 + 1)D. We build some new two-field models, and obtain their exact orbits and exact or numerical field configurations. It is noteworthy that a model presenting triple-kinks and double-flat-top lumps is among those new models. (C) 2014 The Authors. Published by Elsevier B.V.
