Dynamics of Quantum matter

We explore non-equilibrium many-body dynamics in quantum systems that experience symmetry-breaking, topological, or jamming transitions. These systems encompass superconductors, charge-density wave, and magnetic materials.

Experimental Soft Matter Physics

The research is conducted within the “Light and Matter” research program. The interaction of light with matter is one of the most important fields of physics and optical processes are indispensable in many branches of modern industry.

Cueing Up Team Spirit: Billiards Evening

November 14, 2025

Our department recently took a short break from the laboratory to enjoy a teambuilding evening at the billiard hall. As physicists, we could not resist “verifying” some of the most fundamental principles of physics, including linear and angular momentum conservation laws. Forget simulations – we were putting theory to the test with real balls, real cues, and plenty of laughter! While our experimental setups might not have been perfectly controlled, it was a fantastic way to see conservation laws in action (and occasionally witness the unpredictable beauty of collisions). It was a welcome change of pace and a great way to build camaraderie – even if some of our shots were… less than textbook perfect!
