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,…
