Abstract: Many of the most remarkable properties of quantum materials come from the interplay of multiple charge, orbital, and spin degrees of freedom. Probing all of these with a single technique is consequently highly desirable. In this talk, I will describe how resonant inelastic X-ray scattering opens up important new possibilities for measuring these degrees of freedom. This includes observing precursor charge density wave correlations in cuprates, observing orbital hybridization in iridates, and characterizing the spin behavior within the transient state of photo-doped Sr₂IrO₄.
