Project description

Rapid development of the XUV and soft X-ray ultrafast spectroscopic techniques reaching pulse duration down to attoseconds allows to prepare strong superpositions of quantum states. Such possibility opens a new perspective on the electron and spin dynamics driven by strong electron correlation and spin-orbit coupling in the core-excited electronic states. Within this project we develop a density matrix based time-dependent restricted active space configuration interaction method to track such ultrafast dynamics in open quantum systems. A particular focus is put on the possibility to use soft X-ray and XUV light to control the local magnetic (spin) momenta of transition metal centers, potentially opening up new applications in spintronics and material science.
