Optical Quantum Systems

We are a new research group at the Kirchhoff-Institute for Physics

 

Our group explores optical quantum systems to study emergent many-body phenomena.

Quantum fluids of light can be experimentally realized within nanostructured material-filled optical resonators. Utilizing the light-matter interactions in this platform, we conduct fundamental studies on thermodynamics and quantum-statistical effects. We are interested to explore how topological properties can arise in photonic structures under finite-temperature conditions, how complex networks of optical condensates can be employed as physical computers for optimization problems, or how quantum many-body states of light, e.g. photon superfluids, can be synthesised at room temperature. Unravelling such open questions is at the forefront of today’s research in quantum physics and may lead to new applications for future quantum technologies.

You can also contact us directly with any questions.

 

There are PhD and Postdoc positions available in our group. Please contact us to learn more.

We also are always looking for Bachelor and Master students, and offer HiWi jobs.

NEW LIGHT ON QUANTUM PHYSICS

Julian Schmitt recently joined the Kirchhoff Institute for Physics – bringing fresh momentum to the field of quantum optics. With his new research group Optical Quantum Systems, he aims to explore how light and matter behave in the quantum world. Johanna Schwarz, administrative director of the faculty, spoke with him about his research and plans in Heidelberg.
