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.

Dynamics of Quantum matter

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.

Our discovery of the first tunable light modulator for EUV is published in Nature Photonics

Our discovery of the first tunable light modulator for EUV is published in Nature Photonics

February 6, 2024
The absence of efficient light modulators for extreme ultraviolet - EUV and X-ray photons considerably limits their real-life application, particularly when even slight complexity of the beam patterns is required. In ...
