Stable Kink-Kink and Metastable Kink-Antikink Solutions

We construct and study two kink theories. One contains a static 2-kink configuration with controllable binding energy. The other locally stable non-topological solution, which we call lavion. new models are 1D analogs of non-integrable systems in higher dimensions such as the Skyrme model realistic vortex systems. To help theories, derive simple expression for interaction energy between kinks.
