Title: Inter-skyrmion forces
Abstract: One of the first questions that arises when considering emergent particles such as the skyrmion is the influence of one on another: do they repel or attract, and can we show this mathematically. This question was asked about baby skyrmions by Schroers, Piette and Zakrzewski in 1995, and the methods developed were applied to magnetic skyrmions in 2019: they repel, with an exponentially decaying force set by the material anisotropy and external field (and independent of the DMI). In this talk I discuss generalising this method for more exotic textures such as the chiral drop, or more general situations such as applying a tilted magnetic field. The resulting structure of interactions becomes very rich, with the DMI playing an important role.
