B01 Photon-induced structural phase transition controlled by electronic correlations (Samwer, Ulrichs)

Highly correlated electron systems with medium to strong electron-phonon coupling like manganites are strongly interesting because of their rich properties. The topic of this project is to study photon‐induced structural phase transitions due to electronic correlations. This allows in principle to convert light into electronic excitations on certain life times which couple then to the magnetic and phonon system. The long‐term goal is the experimental verification of predicted transient states as the correlated state evolves in time and space after a massive excitation due to light in the ultrafast transmission electron microscope (UTEM).
