Correlations and confinement of excitations in an asymmetric Hubbard ladder
Anas Abdelwahab, Eric Jeckelmann
Correlation functions and low-energy excitations are investigated in the asymmetric two-leg ladder consisting of a Hubbard chain and a noninteracting tight-binding (Fermi) chain us…
Correlated atomic wires on substrates. II. Application to Hubbard wires
Anas Abdelwahab, Eric Jeckelmann, Martin Hohenadler
In the first part of our theoretical study of correlated atomic wires on substrates, we introduced lattice models for a one-dimensional quantum wire on a three-dimensional substrat…
Correlated atomic wires on substrates. I. Mapping to quasi-one-dimensional models
Anas Abdelwahab, Eric Jeckelmann, Martin Hohenadler
We present a theoretical study of correlated atomic wires deposited on substrates in two parts. In this first part, we propose lattice models for a one-dimensional quantum wire on…
