Quantum Condensed Matter Dynamics

Andrea Cavalleri

The Condensed Matter Dynamics group is led by Andrea Cavalleri and focuses on non-equilibrium phenomena in solids. Especially, we investigate how electronic and structural order can emerge as a result external drives, how transitions occur in solids dynamically and how energy flows into and away from a solid. Light-control of superconductivity, ferroelectricity, magnetism and of topological phase transitions have been at the centre of our research.
