| Abstract: |
| In the last years the analysis of the properties of edge-sharing cuprates has motivated scientists to introduce and study models of frustrated spin systems in which the frustration comes from the competition between ferromagnetic and antiferromagnetic behaviour. In some cases such a frustration suggests the introduction of a chiral order parameter in terms of which phase transitions can be analyzed. In this framework we consider the atomistic-to-continuum limit of a two-dimensional Villain-type spin system leading to the emergence of chirality phase transitions and discuss the dependence of some of their geometric properties on the anisotropy of the lattice. |
