PIER Photon Science Colloquium: Probing spin, charge and orbital excitations with inelastic X-ray scattering

Description
Transition metal compounds show many fascinating properties that can be exploited in sensors, next generation electronics, and in catalysis for chemical reactions. The astonishing electronic and magnetic phenomena stem from the delicate interplay of the spin, charge, and orbital degrees of freedom associated with the open-shell transition metal ions.
 
Recent progress in both resonant and non-resonant inelastic X-ray scattering experiments open new possibilities to study these materials. In this talk I will discuss how to quantitatively obtain information about the ground-state wave-function using non-resonant inelastic X-ray scattering as well as how to measure spin, charge and orbital dynamics using resonant inelastic X-ray scattering.
