Topological Solitons Seminar: Vortices and Magnetic Impurities
3 December 2014 13:00 in CM221
It was recently discovered how to introduce electric and magnetic impurities into the critically-coupled Ginzburg-Landau vortex Lagrangian while preserving a moduli space of static solutions. I will focus on magnetic impurities and discuss how they deform both the static solutions and the moduli space metric, which describes slow-motion vortex scattering. I will begin on a flat space background, where only numerical results are possible, before presenting some analytical results for vortices on the hyperbolic plane and the 2-sphere.
