 The single-band Hubbard model has been used to describe the electronic structure of the electron-doped cuprates. However, recent studies suggest that this model does not accurately capture the physics of the material. In particular, quantum Monte Carlo simulations show that the model predicts a charge modulation, which is inconsistent with experimental observations. This suggests that the single-band Hubbard model cannot be used to explain the electronic structure of the electron-doped cuprates. This article was authored by Peji Mai, Nathan S.
