The Condensed Matter Dynamics group is led by Prof. Andrea Cavalleri and focuses on non-equilibrium phenomena in quantum materials. In particular, we investigate how electronic and structural order can emerge as a result of external drives and how transitions occur in complex solids dynamically. Light-control of superconductivity, ferroelectricity, magnetism and topology have been at the centre of our research.
