Prof. Dr. Sebastian Klembt

I am an Assistant Professor (Juniorprofessor) at the Chair for Applied Physics of the Julius-Maximilians-Universität Würzburg. Since 2018, I am pursuing my habilitation in the field of experimental physics. My research focus is to take effects of topological protection known from solid state physics (such as the Quantum Hall or Quantum spin Hall effect) and to bring them to photonic systems. In particular, we have realized the first topological insulator for hybrid light-matter particles: exciton-polaritons. This platform promises unique novel features, new many-body effects and quantum-coherent phenomena in this symbiotic light-matter system. Furthermore, we work on technological implementations of semiconductor based Topological Lasers and Exceptional Point Sensors.

Keywords: Quantum Photonics, Optical Spectroscopy, Light-matter Interactions in Semiconductors, Topological Effects in Photonic Systems, Epitaxy, Technology and Design of Microcavities, Exciton-Polaritons in Lattices, Novel Semiconductor Laser Designs, Novel 2D Semiconductor Materials
