Ideal topological flat bands in chiral symmetric moiré systems from non-holomorphic functions
Siddhartha Sarkar, Xiaohan Wan, Yitong Zhang +1
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…

Symmetry-based classification of exact flat bands in single and bilayer moiré systems
Siddhartha Sarkar, Xiaohan Wan, Shi-Zeng Lin +1
We study the influence of spatial symmetries on the appearance and the number of exact flat bands (FBs) in single and bilayer systems with Dirac or quadratic band crossing points,…
