Abstract:
 'Title: Emergent Spin Vortex Crystals in Frustrated Quantum Magnets (invited to Symposium 3, although fits somewhat better with Symposium 4 and Symposium 6)\r\nAbstract: \r\nIn the past several decades, the focus of condensed matter physics and materials research has been on the so-called strongly correlated electron materials. One of the most striking consequences of strong electron correlations is the emergence of exotic quantum phases of matter. In this talk, I will illustrate the phenomenon of quantum emergence on two examples of appearance of non-trivial spin textures in frustrated quantum magnets – here the term “frustration” refers to the presence of competing interactions that cannot be simultaneously satisfied. This results in complex magnetic states, for instance a three-dimensional \"vortex crystal\" which we predicted theoretically to form on frustrated cubic lattices, and which has recently found an experimental confirmation. We also study the details of non-co!
 llinear magnetic order observed in a quasi-2D material Sr2F2Fe2OS2 and show how it can be understood as a spin vortex crystal.'
