Add to Calendar 2/1/2019 1:00 pm 2/1/2019 America/Chicago Condensed Matter Seminar: "X-ray vision of spins, charges and orbitals for understanding emergent electronic states in complex oxides" DESCRIPTION:

The charge, lattice, orbital and spin 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 resonant inelastic x-ray scattering (RIXS) opens 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 [1], Weyl phonons in FeSi [2], determining how orbitals are modified within LaNiO3-based heterostructures [3] and characterizing the spin behavior within the transient state of photo-doped Sr2IrO4 [4].
