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.

At the opening of the 33. Days of Jožef Stefan, Dragan Mihailović presented a lecture on the self-organization of quantum systems. He discussed how symmetry, topology, causality, and space-time fluctuations shape the ...

JOŽEF STEFAN INSTITUTE

Department of Complex Matter | F7

Understanding complexity through fundamental and applicative research.

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 systems, magnetic materials and heterostructures.

Experimental Soft Matter Physics

Our research comprises experimental investigations of optical phenomena in soft matter, interactions of light with soft matter, as well as possible applications in photonics, information technology and medicine.

Department of Complex Matter

The research within the department of Complex Matter encompasses a variety of research fields, ranging from the synthesis of new materials to fundamental investigations of elementary excitations, self-organising behaviour and adaptive functionality in complex systems. These include anything from nano-biosystems and bio molecules to superconductors and nanowires.

The experimental methods used are suitably diverse, from synthetic chemistry to biomedicine, femtosecond laser spectroscopy and magnetometry. The experimental research within the department is strongly supported by theory.
