Pairing and charge distribution in Emery ladders preserving the ratio of Cu to O atoms
Gökmen Polat, Eric Jeckelmann
We study the Emery model (three-band Hubbard model) for superconducting cuprates on three distinct ladder-like lattices that are supercell of the CuO plane and thus preserve th…

Influence of oxygen orbitals and boundary conditions on the pairing behavior in the Emery model for doped ladders
Gökmen Polat, Eric Jeckelmann
We investigate the Emery model on several ladder-like lattices including two legs of copper d-orbitals and various numbers of oxygen p-orbitals. Pair binding energy, pair spatial s…
