报告摘要

Kagome lattice compounds have attracted extensive attention since they can host a wide variety of exotic phenomena including charge or spin density wave (SDW/CDW), superconductivity (SC), Weyl magnet, spin liquid, and so on. In addition, these kagome materials provide a novel platform to investigate topological electronic states. Recently, a new family of kagome metals AV3Sb5 (A = K, Rb, or Cs) has been discovered, which show coexistence of CDW, superconductivity and anomalous Hall effect, and attracted a huge attention in the communities of condensed matter physics these days. Here I will summarize our recent results on the crystal growth, characterization and physical properties of this family of compounds.
