Minimal Model for the Flat Bands in Copper-substituted Lead Phosphate Apatite

Discussion- In conclusion, two canadian researhcers have proposed a minimal two-band model which reproduces the main features of the Cu dzx and dzy flat bands predicted to appear in a copper-substituted lead apatite. They hope the model facilitates the investigation of the fascinating strongly correlated physics which could be hosted by these bands. As a ...
