Session

Abstract: Spin models describe magnetic properties of materials. In this talk we will examine a 2-d planar spin model (the J 1 − J 2 − J 3 model) which exhibits frustration, a mechanism that leads to complex geometric patterns in the material. A discrete-to-continuum variational analysis allows us to show that the surface tension between different chiral phases is captured by a suitable continuum energy.
