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 supercells of the CuO plane and thus preserve t…
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…
Pair binding and enhancement of pairing correlations in asymmetric Hubbard ladders
Anas Abdelwahab, Gökmen Polat, Eric Jeckelmann
Asymmetric two-leg Hubbard ladders with different on-site interactions and hoppings on each leg are investigated using the density matrix renormalization group method a…
Effective narrow ladder model for two quantum wires on a semiconducting substrate
Anas Abdelwahab, Eric Jeckelmann
We present a theoretical study of two spinless fermion wires coupled to a three dimensional semiconducting substrate. We develop a mapping of wires and substrate onto a system of t…
Magnetic properties of alternating Hubbard ladders
Kaouther Essalah, Ali Benali, Anas Abdelwahab +2
We investigate the Hubbard Hamiltonian on ladders where the number of sites per rung alternates between two and three. These geometries are bipartite, with a non-equal number of si…
Comparative Study of State-of-the-Art Matrix-Product-State Methods for Lattice Models with Large Local Hilbert Spaces
Jan Stolpp, Thomas Köhler, Salvatore R. Manmana +3
Lattice models consisting of high-dimensional local degrees of freedom without global particle-number conservation constitute an important problem class in the field of strongly co…
