The Hubbard model represents the fundamental model for interacting quantum systems and
electronic correlations. Using the two-dimensional half-filled Hubbard model at weak …

Variational Monte Carlo is a many-body numerical method that scales well with system size.
It has been extended to study the Green function only recently by Charlebois and Imada …

Do** a Mott insulator gives rise to unconventional superconducting correlations. Here we
address the interplay between d-wave superconductivity and Mott physics using the two …

A method to calculate the one-body Green's function for ground states of correlated electron
materials is formulated by extending the variational Monte Carlo method. We benchmark …

We study the charge-density-wave order and its competition with superconductivity in the
one-band Hubbard model for high-T c superconducting cuprates. We use cluster dynamical …

We investigate the possibility of spin texture in the bilayer cuprate superconductor Bi 2 Sr 2
CaCu 2 O 8+ δ using cluster dynamical mean-field theory. The one-band Hubbard model …

Cluster perturbation theory is applied to the two-dimensional Hubbard t− t′− t′′− U
model to obtain do** and temperature-dependent electronic spectral function with 4× 4 …

It is still debated whether the low-do** Fermi surface of cuprates is composed of hole
pockets or of disconnected Fermi arcs. Results from cellular dynamical mean field theory (c …

The oxidation of copper does not only lead to an unusable saucepan, but also toone of the
most fascinating family of materials: the cuprates. Their largesuperconducting critical …

Résumé Découverte il y a 35 ans, la supraconductivité dans les cuprates fait, aujourd'hui
encore, tourner toutes les têtes. Qu'il s' agisse d'augmenter leur température critique ou bien …
