报告摘要：
Electronic structure theory for strongly correlated systems (SCSs) is regarded as one of the greatest challenges in molecular quantum chemistry and condensed matter theory. There are continuous efforts in developing various quantum embedding techniques to treat complex SCSs accurately and efficiently. Density-matrix embedding theory (DMET), formulated based on the Schmidt decomposition of Slater determinants, provides a systematic framework to combine low- and high-level quantum chemistry methods to treat strongly correlated systems. In this talk, I will present our recent efforts of further developing and applying DMET-based quantum embedding approaches to strongly correlated single-impurity systems including 3d and 4f single-ion magnets (SIMs) and lanthanide luminescent materials.
