Title:  Interrogating Spins, Charges and Orbitals in Complex Oxides with Resonant X-Rays
Abstract: The charge, spin and orbital degrees of freedom play a crucial role in determining the remarkable properties of transition metal oxide materials, but probing these degrees of freedom is often challenging. In this talk, I will describe how developments in resonant x-ray scattering open up important new possibilities for measuring these degrees of freedom even in extreme cases such as atomically thin heterostructures and ultra-fast transient states. This includes observing precursor charge correlations in cuprates, determining how orbitals are modified within La NiO 3 -based heterostructures and characterizing the spin behavior within the transient state of photo-doped Sr 2 IrO 4. I will end by discussing some perspectives for measuring at mesoscopic time and length scales with coherent x-rays.
