High Chern numbers in a perovskite-derived dice lattice (LaXO(3))(3)/(LaAlO(3))(3)(111) with X = Ti, Mn and Co
The dice lattice, containing a stack of three triangular lattices, has been proposed to exhibit nontrivial flat bands with nonzero Chern numbers, but unlike the honeycomb lattice it is much less studied. By employing density-functional theory (DFT) calculations with an on-site Coulomb repulsion term...
