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.

Time-Resolved Resonant EUV Polarimetry of Magnetic Materials

We are developing new methods for studying the dynamics of complex magnetic materials in 3D and on ultrafast time scales. Utilizing lab-scale laser sources, we have recently built the compact beamline, which provides unique insight into the dynamics of magnetic moments of separate species within a composite system beyond the typical “single-projection” approach. With the new capabilities, we are investigating the prospects for magnetization reversal and the details of magnetization dynamics in technologically relevant ferromagnetic films with high anisotropy.
