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

TL;DR

This paper presents a method to construct two-field scalar models from one-field models using deformation techniques, providing explicit solutions and demonstrating the approach's general applicability.

Contribution

It introduces a systematic procedure to generate coupled two-field models from single-field models via deformation, with explicit topological solutions.

Findings

The deformation procedure successfully generates two-field models from one-field models.

Explicit topological solutions are obtained for various examples.

The method is shown to be broadly applicable to different scalar field theories.

Abstract

In this paper 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.
