Mean Field Study of Superconductivity in the Square Lattice - Model with Three-Site Hopping
Ke Yang, Qianqian Chen, Lei Qiao +1
It remains an open question whether the two-dimensional single-band pure Hubbard model and its related pure - model truly capture the superconducting order in cuprates. Recen…

Phase Diagram of the Square-Lattice -- Model for Electron-Doped Cuprates
Qianqian Chen, Lei Qiao, Fuchun Zhang +1
Motivated by significant discrepancies between experimental observations of electron-doped cuprates and numerical results of the Hubbard and - models, we investigate the role…
