Minimal model for the flat bands in copper-substituted lead phosphate apatite: Strong diamagnetism from multiorbital physics
Minimal model for the flat bands in copper-substituted lead phosphate apatite: Strong diamagnetism from multiorbital physics
The claims that a copper-substituted lead apatite, denoted as ${\mathrm{CuPb}}_{9}{({\mathrm{PO}}_{4})}_{6}{(\mathrm{OH})}_{2}$, could be a room-temperature superconductor have led to intense research activity. While other research groups did not confirm these claims, and the hope of realizing superconductivity in this compound has all but vanished, other findings have emerged which motivate further …
