  ABSTRACT: In this study, we systematically investigate the regulatory effects of electronic correlations on multiple ordered states in kagome superconductors based on the single-orbital extended Hubbard model. Our results demonstrate that the intersite Coulomb interaction V serves as a key factor driving the formation of charge density wave (CDW): The CDW phase emerges as the thermodynamically stable ground state when V exceeds a critical threshold (~0.6 eV). In contrast, the on-site Coulomb interaction U suppresses CDW formation, revealing a clear competitive interplay between U and V. Furthermore, a sufficiently strong on-site Coulomb interaction U (U ≥ 6 eV) induces a stable intertwined charge-spin density wave (SCDW) coexisting with the CDW background, while the intersite Coulomb interaction V tends to suppress magnetic order. This study elucidates the interplay and competition mechanisms between charge order and spin order in kagome lattice systems, providing a theoretical foundation for the tunability of quantum states in this material family.
