Author(s): Gökmen Polat and Eric Jeckelmann We study the Emery model (three-band Hubbard model) for superconducting cuprates on three distinct ladderlike lattices that are supercells of the ${\mathrm{CuO}}_{2}$ plane and thus preserve the ratio of copper to oxygen atoms. Using the density-matrix renormalization group method we confirm that th… [Phys. Rev. B 114, 185111] Published Wed Sep 09, 2026
