First-principles molecular transport calculation for the benzenedithiolate molecule
M. Rumetshofer, G. Dorn, L. Boeri +2
A first-principles approach based on Density Functional Theory and Non-Equilibrium Green's functions is used to study the molecular transport system consisting of benzenedithiolate…
Fate of the false Mott-Hubbard transition in two dimensions
T. Schäfer, F. Geles, D. Rost +6
We have studied the impact of non-local electronic correlations at all length scales on the Mott-Hubbard metal-insulator transition in the unfrustrated two-dimensional Hubbard mode…
Strong enhancement of d-wave superconducting state in the three-band Hubbard model coupled to an apical oxygen phonon
Z. B. Huang, H. Q. Lin, E. Arrigoni
We study the hole binding energy and pairing correlations in the three-band Hubbard model coupled to an apical oxygen phonon, by exact diagonalization and constrained-path Monte Ca…
The superconducting gap in the Hubbard model and the two gap energy scales in high-Tc cuprates
M. Aichhorn, E. Arrigoni, Z. B. Huang +1
Recent excperiments (ARPES, Raman) suggest the presence of two distinct energy gaps in high-Tc superconductors (HTSC), exhibiting different doping dependences. Results of a variati…
Variational cluster approach to the Hubbard model: Phase-separation tendency and finite-size effects
M. Aichhorn, E. Arrigoni, M. Potthoff +1
Using the variational cluster approach (VCA), we study the transition from the antiferromagnetic to the superconducting phase of the two-dimensional Hubbard model at zero temperatu…
Weak phase separation and the pseudogap in the electron-doped cuprates
M. Aichhorn, E. Arrigoni
We study the quantum transition from an antiferromagnet to a superconductor in a model for electron- and hole-doped cuprates by means of a variational cluster perturbation theory a…
