DOI: 10.1103/physrevlett.127.207205
Abstract: Characterizing non-local magnetic fluctuations in materials with strong electronic Coulomb interactions remains one of the major outstanding challenges of modern condensed matter theory. Here, we address the spatial symmetry and orbital structure of magnetic fluctuations… read more here.
