Topological flat band, Dirac fermions and quantum spin Hall phase in 2D Archimedean lattices
F. Crasto de Lima, Gerson J. Ferreira, R. H. Miwa
Materials with designed properties arises in a synergy between theoretical and experimental approaches. In this study we explore the set of Archimedean lattices forming a guidance…

Double flat bands in kagome twisted bilayers
F. Crasto de Lima, R. H. Miwa, E. Suárez Morell
We have studied how a generic bilayer kagome lattice behave upon layer rotation. We employed a Tight Binding model with one orbital per site and found (i) for low rotational angles…
