Rev. Lett., Scientific Report,Phys. Rev. B等SCI期刊上,部分工作被综合媒体报道,并被同行验证。
  研究介绍  
我们主要研究具有非平庸拓扑性和强电子关联性的量子材料体系。通过拓展量子多体理论并结合大规模数值模拟,我们试图理解这些材料体系的基态以及低能激发态的电学和磁学性质,并解释包括角分辨光电子谱及扫描隧道显微镜在内的实验观测结果。我们的研究方法包括但不局限于:dynamical mean-field theory (DMFT), cluster DMFT, dynamical cluster approximation, dual-fermion approach, non-local expansion and parquet equations等。
