摘 要:
Magnetic skyrmions are topological solitons which occur in a large class of magnetic materials and which are currently attracting much attention in the condensed matter community because of their possible use in future magnetic information storage technology. This talk is about the geometry underlying the theory of chiral magnetic skyrmions, and in particular the observation that mathematical models for chiral skyrmions can be re-written as non-abelian gauged sigma-models. For particular critical values of the coupling parameters they can be solved exactly in terms of holomorphic data. I will explain the gauge-theoretical interpretation and show that the exact solutions can also be used to obtain new numerical solutions away from critical coupling.
