Flat bands and unconventional superconductivity in a simple model of metal-organic frameworks
M. F. Ohlrich, E. M. Makaresz, H. L. Nourse +1
The superconducting metal-organic framework Cu-BHT forms a kagome lattice with metals at the vertices and ligands along the bonds. This bipartite motif is common in reticular mater…

symmetry breaking metal-insulator transitions in a flat band in the half-filled Hubbard model on the decorated honeycomb lattice
H. L. Nourse, Ross H. McKenzie, B. J. Powell
We study the single-orbital Hubbard model on the half-filled decorated honeycomb lattice. In the non-interacting theory at half-filling the Fermi energy lies within a flat band whe…
