Fig. 3: Bandwidth variation and Fibonacci lattice on the sphere.
From: Flat bands on a spherical surface from Landau levels to giant-quantum-number orbitals
Energy-bandwidth as a function of 1/Nδ and the number of orbitals NO = 101, where the peak of the line representing the lowest Landau level (LLL) corresponds to Nδ = 2Q = 100. Nδ is the number of delta potentials and Q is the strength of the magnetic monopole. The blue solid line represents the LLL, while the purple dash-dotted line denotes the flat band with Q = 0. The orange dots indicate a schematic Fibonacci lattice arranged on the surface of the blue sphere. Source data are provided in the Supplementary Data.
