While later experiments put this proposal out of business\, thinking of topological solitons as em erging building blocks or artificial atoms is very appealing. Indeed\, more recent developments\, that started around the 1960's\, have demonstrated t hat nature has plenty of room for finding updated versions of aether. The a ether of quantum magnets is the vector field of magnetic moments\, whose to pological solitons can be regarded as emergent mesoscale atoms. Like real a toms\, these solitons form periodic arrays or crystals whose organizing pri nciples are dictated by symmetry\, anisotropy and competing microscopic int eractions. Moreover\, these magnetic textures generate an effective compact U(1) gauge field\, minimally coupled to the conduction electrons\, that ca n reach astronomical values.\n\nWe will see that the emergent magnetic fiel d is related to a geometric property known as real space Berry curvature\, whose general (covariant) form must be modified in the presence of relativi stic spin-orbit coupling.
