Line Plot from Scientific Research

Charge-ordered states (formulated using Monte Carlo simulations) that arise in the Γ (pink and purple) and K (red) moire lattices for V E = 0, for which the energy of the K-derived band is below both Γ-derived bands (ϵ K < ϵ B ). The Γ B sites are spatially aligned with the K sites in the x – y plane. Holes are first loaded into the Γ A sites up to ν h = 1 and into the Γ B sites for ν h > 1. Schematic to the right illustrates the hole energy versus density of states (DOS) for each charge-ordered state shown in these data. The lower Hubbard band (LHB) and upper Hubbard band (UHB) form for ν h = 1, whereas a charge gap Δ opens up for correlated states that form for non-integer filling.
