Ultrafast x-ray scattering: chemical dynamics and beyond

Date Mo, 09.07.2018 - Mo, 09.07.2018
Time 16:45
Speaker Prof. Adam Kirrander, School of Chemistry, University of Edinburg, UK
Location ETH Hönggerberg, HPF G6
Program Abstract:
Ultrafast scattering using X-ray Free-Electron Lasers (XFELs) is an exciting development in AMO physics and chemical reaction dynamics [1]. The elastic component of the scattering provides a direct probe of structural dynamics, as demonstrated in recent experiments [2,3] (Fig. 1a). The experiments are supported by ab initio electronic structure calculations and quantum molecular dynamics simulations.

From a theoretical point of view, the standard expressions for X-ray scattering are modified by the quantum superposition inherent in ultrafast experiments [4]. I will demonstrate how the wavepacket limits the spatial resolution attainable in diffraction experiments [5] (see Fig. 1b), and discuss how interference effects might make it possible to characterize electronic coherences during the dynamics.
