Correlated Quantum Matter and Materials

Welcome to CQM2 Group!

Our research group at Beihang University is focusing on many-body physics such as correlation effects and topological phases in quantum matter. Strong interactions among atomic particles can lead to materials, such as some high-temperature superconductors, with unusual electronic and magnetic properties. We aim to develop quantum many-body simulation techniques, e.g., tensor networks, renormalization group, and deep learning techniques, that provide reliable and accurate numerical access to thermal and dynamical properties of correlated systems. With state-of-the-art methods, we explore novel states of matter and reveal underlying manybody theory, in correlated materials that could possibily lead to intriguing applications in future quantum technology.
