High-temperature superconductivity, with transition temperatures up to≈ 134 K at ambient
pressure, occurs in layered cuprate compounds. The conducting CuO2 planes, which are …

In non-interacting systems, bands from non-trivial topology emerge strictly at half-filling and
exhibit either the quantum anomalous Hall or spin Hall effects. Here we show using …

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 …

Typical Wannier-function downfolding starts with a mean-field or density functional set of
bands to construct the Wannier functions. Here, we carry out a controlled approach, using …

We determine the spin and charge orders in the ground state of the doped two-dimensional
(2D) Hubbard model in its simplest form, namely with only nearest-neighbor hop** and on …

Understanding quantum materials—solids in which interactions among constituent electrons
yield a great variety of novel emergent quantum phenomena—is a forefront challenge in …

We study the pairing properties of the two-dimensional tt′-t ″-J model, where t′ and t
″are second and third neighbor hop**s, at a do** level x≈ 0.1. Recent studies of the …

Competing and intertwined orders including inhomogeneous patterns of spin and charge
are observed in many correlated electron materials, such as high-temperature …

We briefly review methods for modeling correlated systems. The concept of correlations is of
fundamental physical importance for systems such as Mott±Hubbard insulators, high …

There is growing evidence that the hole-doped single-band Hubbard and t− J models do not
have a superconducting ground state reflective of the high-temperature cuprate …
