DYNAMICS OF BABY SKYRMIONS

Baby Skyrmions are topological solitons in a (2+1)-dimensional field t heory which resembles the Skyrme model in important respects. We apply some of the techniques and approximations commonly used in discussion s of the Skyrme model to the dynamics of baby Skyrmions and directly t est them against numerical simulations. Specifically we study the effe ct of spin on the shape of a single baby Skyrmion, the dependence of t he forces between two baby Skyrmions on the baby Skyrmions' relative o rientation and the forces between two baby Skyrmions when one of them is spinning.
