In the Low-Dimensional Quantum Materials Lab, we conduct theoretical and experimental research on light-matter interaction in low-dimensional quantum materials (2D, 1D, 0D), with a particular focus on the strong coupling regime and its manifestations in optical and transport properties. Theoretical research ranges from the development of novel ab initio techniques for quantitative modeling of quantum electrodynamics to symmetry analysis of new phases in quantum materials. Experiments involve both measurements of ultrafast nonlinearities using pump-probe techniques and quantum measurements of photon correlations induced by light-matter interactions. The Lab was established in 2017 as part of the Mega-grant “Hybrid light-matter states in low-dimensional quantum materials with specified characteristics” (14.Y26.31.0015).
