Domain walls, superconductor vortices, magnetic skyrmions, liquid crystal defects... all these phenomena and many more, ranging from high energy to nuclear physics to condensed matter, come under the umbrella of topological solitons. In all cases, something topological stops some localised pocket of energy, the topological soliton, from collapsing in on itself. These topological solitons are fascinating objects of study. On a theoretical level because in many ways they act like emergent particles, and on a practical level as possible information carriers of the future. I will summarise why we are interested in topological solitons, where they appear and what kind of questions we are interested in asking, with examples in my own research.
