Ideal topological flat bands in chiral symmetric moiré systems from non-holomorphic functions

Abstract Recent studies on topological flat bands and their fractional states have revealed increasing similarities between moiré flat bands and Landau levels (LLs). For instance, like the lowest LL, topological exact flat bands with ideal quantum geometry can be constructed using the same holomorph...
