Hidden mechanism for embedding the flat bands of Lieb, kagome, and checkerboard lattices in other structures
Hidden mechanism for embedding the flat bands of Lieb, kagome, and checkerboard lattices in other structures
The interplay of hopping parameters that can give rise to flat bands in consequence of quantum interference in electronic, photonic, and other interesting materials has become an extensively studied topic. Most of the recognized structures having flat bands are the lattices that can be understood by the mathematical theory of …
