WebDec 3, 2024 · The low-energy narrow bands were shown to be well described by an effective tight-binding model on the honeycomb lattice (the dual of the triangular Moiré superlattice) with a local orbital degree of freedom. In this paper, we perform a strong-coupling analysis of the proposed (px, py) two-orbital extended Hubbard model on the honeycomb lattice. Kagome compound YMn6Sn6 has a hexagonal structure with space group P6/mmm (No. 191). It contains three kinds of Sn sites, stacking of Y-Sn3 layer and Mn–Sn1–Sn2–Sn1–Mn slab, with double Mn kagome lattice layers as shown in Fig. 1c. The Sn2 atoms form the honeycomb lattice located at the … See more In order to investigate the kagome lattice related topological electronic structure, we measured the band structures in the 1st BZ at kz ~ 0 plane along with … See more A feature that is faint in the 1st BZ but more clearly visible in the 2nd BZ is the existence of another flat band near EF at the BZ center, labeled as FB2 in Fig. 4.
