Incommensurate magnetic order in the Hubbard model and its possible connection to high-Tc cuprate superconductors
The ground state of the two-dimensional Hubbard model is analyzed by including a possible incommensurate spiral order by using a functional renormalization group scheme and mean-field theory. We discuss a connection to the drop of the Hall number and quantum oscillation measurements in high-Tc cuprate superconductors. Details are seen in PRL 116, 096402 (2016) and PRL 117, 187001 (2016).
