The Hubbard model, which augments independent-electron band theory with a single parameter to describe electron-electron correlations, is widely regarded to be the "standard model" of condensed-matter physics. The model has been remarkably successful at addressing a range of correlation phenomena in solids, but it neglects many behaviors that occur in real materials, such as phonons, long-range interactions, and, in its simplest form, multiorbital effects. Here, we use ab initio electronic…

Materials Informatics Approach to the Identification of One-Band Correlated Materials Analogous to the Cuprates

- Physics, Materials SciencePhysical Review X
- 2019

One important yet exceedingly rare property of the cuprate high-temperature superconductors is the presence of a single correlated $d$ band in the low-energy spectrum, leading to the one-band Hubbard…

Hubbard models on general lattices: a dynamical cluster approximation approach
