Session Abstract

This symposium will focus on the crystallographic and crystal symmetry aspects of quantum magnets, spin liquids and fractionalization, spin textures and topological excitations such as skyrmions, merons and emergent magnetic monopoles, Weyl and Dirac fermions as well as the corresponding semimetals.  Experimental, theoretical, information theoretic discovery, and computational aspects enhancing our understanding of these novel quantum materials will be discussed.
