Kinklike structures in scalar field theories: From one-field to two-field models

In this Letter we study the possibility of constructing two-field models from one-field models. The idea is to start with a given one-field model and use the deformation procedure to generate another one-field model, and then couple the two one-field models nontrivially, to get to a two-field model, together with some explicit topological solutions. We show with several distinct examples that the procedure works nicely and can be used generically. (c) 2013 Elsevier B.V. All rights reserved.
