Magnetic and charge orders in the ground state of the Emery model -- accurate numerical results
Adam Chiciak, Ettore Vitali, Shiwei Zhang
We perform extensive auxiliary-field quantum Monte Carlo (AFQMC) calculations for the three-band Hubbard (Emery) model in order to study the ground-state properties of Copper-Oxyge…

Metal-insulator transition in the ground-state of the three-band Hubbard model at half-filling
Ettore Vitali, Hao Shi, Adam Chiciak +1
The three-band Hubbard model is a fundamental model for understanding properties of the Copper-Oxygen planes in cuprate superconductors. We use cutting-edge auxiliary-field quantum…

Magnetic orders in the hole doped three-band Hubbard model: spin spirals, nematicity, and ferromagnetic domain walls
Adam Chiciak, Ettore Vitali, Hao Shi +1
The Copper-Oxygen planes in cuprates have been at the center of the search for a theory of high-temperature superconductivity. We conduct an extensive study of the ground state of…
