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.

Theoretical studies on the nanoscale

We employ a range of methods for modeling and simulating many-body quantum systems. These methods encompass analytical techniques, GL-based modeling, classical simulations utilizing Monte Carlo techniques, as well as simulations of quantum dynamics utilizing quantum computer processors.
