Coulomb exchange as source of Kitaev and off-diagonal symmetric anisotropic couplings
Abstract Exchange underpins the magnetic properties of quantum matter. In its most basic form, it occurs through the interplay of Pauli’s exclusion principle and Coulomb repulsion, being referred to as Coulomb or direct exchange. Pauli’s exclusion principle combined with inter-atomic electron hoppin...
