QMat was created in July 2020 in the University of Oldenburg. Our aim is to research on novel quantum materials to exploit their advantages when interfaced with engineered states of light. One central focus is the investigation of the physics and optical properties of novel two-dimensional materials and van-der-Waals Heterostructures. In those materials, we study many-body effects and light-matter coupling phenomena, including Bose-Einstein Condensation, superfluidity, topological phenomena and single photon emission.
