Autor: Kumar, Umesh, Nag, Abhishek, Li, Jiemin, Robarts, H. C., Walters, A. C., García-Fernández, Mirian, Saint-Martin, R., Revcolevschi, A., Schlappa, Justine, Schmitt, Thorsten, Johnston, Steve, Zhou, Ke-Jin

Resonant inelastic x-ray scattering (RIXS) is an evolving tool for investigating spin dynamics of strongly correlated materials, which complements inelastic neutron scattering. Both techniques have found that non-spin-conserving (NSC) excitations in

Resonant inelastic X-ray scattering (RIXS) is a powerful probe of elementary excitations in solids. It is now widely applied to study magnetic excitations. However, its complex cross-section means that RIXS has been more difficult to interpret than i

Copper-oxide high TC superconductors possess a number of exotic orders co-existing with or proximal to superconductivity, whose quantum fluctuations may account for the unusual behaviors of the normal state, even affecting superconductivity. Yet, spe
