Matryoshka Skyrmions Original Research Article

We construct a stable Skyrmion in image dimensions as a sine-Gordon kink inside a domain wall within a domain wall in an image sigma model with hierarchical mass terms without the Skyrme term. We also find that higher dimensional Skyrmions can stably exist with a help of non-Abelian domain walls in an image model with hierarchical mass terms without a Skyrme term, which leads to a matryoshka structure of Skyrmions.
