Ultrafast dynamics of elementary processes

Ultrafast dynamics of elementary processes in solids and at interfaces with specific focus on the interactions between electrons, phonons and spins: This line of research addresses the dynamics of elementary processes on their relevant time scales, employing ultrafast laser spectroscopy (with, typically, femtosecond time resolution). Both existing and newly developed spectroscopic techniques are used to study the electronic structure, excited state dynamics, optically induced phase transitions and low-energy excitations including lattice dynamics and spin dynamics in solids and at interfaces.
