2. Coherent Correlation Imaging: An new tool for High-Resolution Imaging of Stochastic Dynamics

Prof. Stefan Eisebitt (Max-Born Institute, Berlin, Germany)

Coherent scattering of x-rays allows to obtain real space information via (iterative) phasing of the diffraction pattern or via direct phase detection by interference with a reference beam (holography). Regarding „movies“ of dynamic processes, reproducibly triggered dynamics is accessible via pump-probe schemes, as they allow to collect sufficient statistics via repetition of the experiment....

3. Condensed-phase chemical dynamics with ultrashort soft- and hard X-rays

Dr Wojciech Gawelda (Univ. Autonoma Madrid & IMDEA nanoscience)

31/05/2021, 09:45

In this talk I will try to give a brief overview of recent progress in time-resolved implementation of X-ray spectroscopic and scattering methods at X-ray free electron lasers and synchrotrons. I will focus the applications on condensed-phase chemical systems and timescales spanning from femtoseconds to nanoseconds.

4. Ultrafast lattice, electron and spin dynamics

Prof. Urs Staub (Swiss Light Source, Paul Scherrer Institute)

X-ray methods are powerful to study lattice, electron and spin properties of materials and get information on the dynamics by spectroscopic techniques in the steady state. In recent years, X-ray Free Electron Lasers extended the view on the dynamics to the ultrafast time scale, as these sources provide us with ultrashort fs x-ray pulses that extend spectroscopic techniques into time domain,...
