The Hubbard model is the simplest model of interacting fermions on a lattice and is of similar
importance to correlated electron physics as the Ising model is to statistical mechanics or the …

Strong electronic correlations pose one of the biggest challenges to solid state theory.
Recently developed methods that address this problem by starting with the local, eminently …

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

The relationship between the pseudogap and underlying ground-state phases has not yet
been rigorously established. We investigated the doped two-dimensional Hubbard model at …

Understanding the electron pairing in hole-doped cuprate superconductors has been a
challenge, in particular because the “normal” state from which it evolves is unprecedented …

We introduce a method for summing Feynman's perturbation series based on diagrammatic
Monte Carlo that significantly improves its convergence properties. This allows us to …

Recently, above-room-temperature superconductivity was reported in the Cu-doped lead
apatite Pb 10− x Cu x (PO 4) 6 O, dubbed LK-99. By relaxing the structure with Cu …

Understanding electronic properties that violate the Landau Fermi liquid paradigm in
cuprate superconductors remains a major challenge in condensed-matter physics. The …

One of the distinctive features of hole-doped cuprate superconductors is the onset of a
“pseudogap” below a temperature T*. Recent experiments suggest that there may be a …

Motivated by the recently discovered high-T c nickelate superconductor La 3 Ni 2 O 7, we
investigate the S±-wave superconductivity (SC) in a two-dimensional Hubbard model on a …
