Query: Double flat bands in kagome twisted bilayers   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, and at low energies, the same flat bands
structure like in twisted bilayer graphene; though, for a larger value of the
magic angle. Moreover, (ii) at high energies, due to the superstructure
symmetry regions, we found the characteristics three band dispersion of the
kagome lattice. In the latter, its band width decreases for lower angles
confining them within a few meV. Therefore, we found in twisted kagome lattice
the coexistence of two sets of flat bands in different energies and lying in
different spatial regions of the bilayer system.
