Supercell Band Calculations and Correlation for High-𝑇_𝐶 Copper Oxide Superconductors

Figure 3

An example of the 2D NFE bands along (𝑘,0) and (𝑘,𝑘) for 𝑞_𝑥=𝑞_𝑦=0.075 and 𝑉_𝑞= 20 mRy (full line). The FE band without potential perturbations (𝑉_𝑞= 0) is shown by the broken line. The thin horizontal line is at the DOS minimum, which is situated at 0.15 holes/cell.
