Three-dimensional solitons in magnetism, nuclei and particle physics — •Paul Sutcliffe — Durham University, Durham, UK.

Magnetic Skyrmions are two-dimensional topological solitons that are analogous to the three-dimensional Skyrmions introduced by Skyrme in the context of high energy particle physics. I shall discuss the similarities and differences between these two kinds of Skyrmions, together with recent progress on using three-dimensional Skyrmions to describe nuclei. Finally, I shall discuss the possibility of three-dimensional topological solitons in magnetism, called Hopfions, and explain their relation to both types of Skyrmion.
