 sential for developing practical quantum applications. However\, achieving
  such control remains challenging because complex crystal lattices are dif
 ficult to modify with atomic-scale precision. The recently discovered laye
 red kagome metals AV3Sb5 (A = K\, Rb\, Cs)\, which host a cascade of novel
  quantum states\, have attracted significant interest. In addition\, magne
 tic kagome metals have emerged as ideal platforms for investigating the in
 terplay between spin and charge degrees of freedom. In this talk\, I will 
 present our recent work on the atomically precise engineering of quantum s
 tates in kagome metals using ultralow-temperature scanning tunneling micro
 scopy/spectroscopy (STM/STS). First\, I will discuss the discovery of emer
 gent superconductivity and a primary pair-density wave (PDW) at the recons
 tructed surface associated with the bulk charge-density-wave (CDW) order i
 n kagome metal CsV3Sb5. Next\, I will demonstrate the emergence of a spati
 ally anisotropic Kondo resonance intertwined with the superconducting gap\
 , enabled by introducing magnetic Cr impurities into the kagome supercondu
 ctor CsV3Sb5 [2]. Finally\, I will show the unconventional spin-intertwine
 d charge density wave (CDW) in magnetic kagome metal GdTi3Bi4 [3]. Our fin
 dings provide a pathway for manipulating novel many-body states in kagome 
 metals. References：[1] X. Han\, H. Chen#*\, H.-J. Gao* et al. Nature Na

 sor from 2020 to 2026. He has recently joined Hefei National Laboratory as
  a full professor. His research focus on ultra-low-temperature\, high-magn
 etic-field scanning tunneling microscopy/spectroscopy\, with particular em
 phasis on atomic-scale manipulation of low-dimensional quantum structures\
 , such as graphene origami\, and emergent quantum phenomena in correlated 
 and topological materials\, including spin–orbit polarons and pair-densi
 ty waves in kagome-lattice materials.\n\nhttps://indico-tdli.sjtu.edu.cn/e
