报告摘要：Recent experimental investigations have identified fascinating electronic orders in kagome materials, such as intriguing superconductivity, charge density wave (CDW) and nematicity. Notably, there is evidence of spontaneous time-reversal symmetry (TRS) breaking within the CDW phase, though its origins remain elusive. In this talk, I will first briefly review the exotic properties of these kagome superconductors. Then, I will talk about the effect model and the unique sublattice texture associated with van Hove singularities in the kagome lattice, which turns out to have significant effect on the correlated states. Finally, I will focus on our proposed scenario to realize a TRS breaking CDW in kagome lattice. Potential experimental implications will be also discussed.
