Spin-Orbital Excitations in Ca${}_2$RuO${}_4$ Revealed by Resonant Inelastic X-ray Scattering

L. Das, F. Forte, R. Fittipaldi +19

The strongly correlated insulator Ca${}_2$RuO${}_4$ is considered as a paradigmatic realization of both spin-orbital physics and a band-Mott insulating phase, characterized by orbita…
