Welcome to the THz Structural Dynamics group …
We, the team of the new THz structural dynamics group, are obviously fascinated about structural dynamics. Why that? Material properties and chemical reactions are fundamentally determined by the spatial arrangement of atoms, ions or molecules. If we can modulate or change this spatial structure on ultrafast time scales, we can control properties on demand or even discover new material features. For this, we generate highly intense and phase stable laser pulses in the THz and midinfrared spectral range, which enable us to coherently drive specific structural dynamics on their fundamental time and energy scales. Furthermore, we want to explore tailored lattice trajectories, which may help to steer solids into hidden states. Currently, we are focusing on phonon anharmonicities, molecular orientations in solids and dynamically disordered systems.
